CVE-2022-41725 | 2 Golang, Redhat | 19 Go, Ansible Automation Platform, Cert Manager and 16 more | 2025-03-07 | 7.5 High |
A denial of service is possible from excessive resource consumption in net/http and mime/multipart. Multipart form parsing with mime/multipart.Reader.ReadForm can consume largely unlimited amounts of memory and disk files. This also affects form parsing in the net/http package with the Request methods FormFile, FormValue, ParseMultipartForm, and PostFormValue. ReadForm takes a maxMemory parameter, and is documented as storing "up to maxMemory bytes +10MB (reserved for non-file parts) in memory". File parts which cannot be stored in memory are stored on disk in temporary files. The unconfigurable 10MB reserved for non-file parts is excessively large and can potentially open a denial of service vector on its own. However, ReadForm did not properly account for all memory consumed by a parsed form, such as map entry overhead, part names, and MIME headers, permitting a maliciously crafted form to consume well over 10MB. In addition, ReadForm contained no limit on the number of disk files created, permitting a relatively small request body to create a large number of disk temporary files. With fix, ReadForm now properly accounts for various forms of memory overhead, and should now stay within its documented limit of 10MB + maxMemory bytes of memory consumption. Users should still be aware that this limit is high and may still be hazardous. In addition, ReadForm now creates at most one on-disk temporary file, combining multiple form parts into a single temporary file. The mime/multipart.File interface type's documentation states, "If stored on disk, the File's underlying concrete type will be an *os.File.". This is no longer the case when a form contains more than one file part, due to this coalescing of parts into a single file. The previous behavior of using distinct files for each form part may be reenabled with the environment variable GODEBUG=multipartfiles=distinct. Users should be aware that multipart.ReadForm and the http.Request methods that call it do not limit the amount of disk consumed by temporary files. Callers can limit the size of form data with http.MaxBytesReader. | ||||
CVE-2022-41724 | 2 Golang, Redhat | 20 Go, Ansible Automation Platform, Cert Manager and 17 more | 2025-03-07 | 7.5 High |
Large handshake records may cause panics in crypto/tls. Both clients and servers may send large TLS handshake records which cause servers and clients, respectively, to panic when attempting to construct responses. This affects all TLS 1.3 clients, TLS 1.2 clients which explicitly enable session resumption (by setting Config.ClientSessionCache to a non-nil value), and TLS 1.3 servers which request client certificates (by setting Config.ClientAuth >= RequestClientCert). | ||||
CVE-2022-3277 | 2 Openstack, Redhat | 3 Neutron, Openstack, Openstack Platform | 2025-03-07 | 6.5 Medium |
An uncontrolled resource consumption flaw was found in openstack-neutron. This flaw allows a remote authenticated user to query a list of security groups for an invalid project. This issue creates resources that are unconstrained by the user's quota. If a malicious user were to submit a significant number of requests, this could lead to a denial of service. | ||||
CVE-2022-4134 | 2 Openstack, Redhat | 2 Glance, Openstack | 2025-03-06 | 2.8 Low |
A flaw was found in openstack-glance. This issue could allow a remote, authenticated attacker to tamper with images, compromising the integrity of virtual machines created using these modified images. | ||||
CVE-2022-3101 | 2 Openstack, Redhat | 3 Tripleo Ansible, Openstack, Openstack For Ibm Power | 2025-02-25 | 5.5 Medium |
A flaw was found in tripleo-ansible. Due to an insecure default configuration, the permissions of a sensitive file are not sufficiently restricted. This flaw allows a local attacker to use brute force to explore the relevant directory and discover the file, leading to information disclosure of important configuration details from the OpenStack deployment. | ||||
CVE-2022-3146 | 2 Openstack, Redhat | 3 Tripleo Ansible, Openstack, Openstack For Ibm Power | 2025-02-25 | 5.5 Medium |
A flaw was found in tripleo-ansible. Due to an insecure default configuration, the permissions of a sensitive file are not sufficiently restricted. This flaw allows a local attacker to use brute force to explore the relevant directory and discover the file. This issue leads to information disclosure of important configuration details from the OpenStack deployment. | ||||
CVE-2024-34069 | 2 Palletsprojects, Redhat | 5 Werkzeug, Ceph Storage, Openshift and 2 more | 2025-02-21 | 7.5 High |
Werkzeug is a comprehensive WSGI web application library. The debugger in affected versions of Werkzeug can allow an attacker to execute code on a developer's machine under some circumstances. This requires the attacker to get the developer to interact with a domain and subdomain they control, and enter the debugger PIN, but if they are successful it allows access to the debugger even if it is only running on localhost. This also requires the attacker to guess a URL in the developer's application that will trigger the debugger. This vulnerability is fixed in 3.0.3. | ||||
CVE-2021-28235 | 2 Etcd, Redhat | 2 Etcd, Openstack | 2025-02-18 | 9.8 Critical |
Authentication vulnerability found in Etcd-io v.3.4.10 allows remote attackers to escalate privileges via the debug function. | ||||
CVE-2023-45803 | 3 Fedoraproject, Python, Redhat | 8 Fedora, Urllib3, Enterprise Linux and 5 more | 2025-02-13 | 4.2 Medium |
urllib3 is a user-friendly HTTP client library for Python. urllib3 previously wouldn't remove the HTTP request body when an HTTP redirect response using status 301, 302, or 303 after the request had its method changed from one that could accept a request body (like `POST`) to `GET` as is required by HTTP RFCs. Although this behavior is not specified in the section for redirects, it can be inferred by piecing together information from different sections and we have observed the behavior in other major HTTP client implementations like curl and web browsers. Because the vulnerability requires a previously trusted service to become compromised in order to have an impact on confidentiality we believe the exploitability of this vulnerability is low. Additionally, many users aren't putting sensitive data in HTTP request bodies, if this is the case then this vulnerability isn't exploitable. Both of the following conditions must be true to be affected by this vulnerability: 1. Using urllib3 and submitting sensitive information in the HTTP request body (such as form data or JSON) and 2. The origin service is compromised and starts redirecting using 301, 302, or 303 to a malicious peer or the redirected-to service becomes compromised. This issue has been addressed in versions 1.26.18 and 2.0.7 and users are advised to update to resolve this issue. Users unable to update should disable redirects for services that aren't expecting to respond with redirects with `redirects=False` and disable automatic redirects with `redirects=False` and handle 301, 302, and 303 redirects manually by stripping the HTTP request body. | ||||
CVE-2024-1135 | 2 Benoitc, Redhat | 7 Gunicorn, Ansible Automation Platform, Openshift and 4 more | 2025-02-13 | N/A |
Gunicorn fails to properly validate Transfer-Encoding headers, leading to HTTP Request Smuggling (HRS) vulnerabilities. By crafting requests with conflicting Transfer-Encoding headers, attackers can bypass security restrictions and access restricted endpoints. This issue is due to Gunicorn's handling of Transfer-Encoding headers, where it incorrectly processes requests with multiple, conflicting Transfer-Encoding headers, treating them as chunked regardless of the final encoding specified. This vulnerability allows for a range of attacks including cache poisoning, session manipulation, and data exposure. | ||||
CVE-2023-5366 | 2 Openvswitch, Redhat | 7 Openvswitch, Enterprise Linux, Fast Datapath and 4 more | 2025-02-13 | 7.1 High |
A flaw was found in Open vSwitch that allows ICMPv6 Neighbor Advertisement packets between virtual machines to bypass OpenFlow rules. This issue may allow a local attacker to create specially crafted packets with a modified or spoofed target IP address field that can redirect ICMPv6 traffic to arbitrary IP addresses. | ||||
CVE-2023-46136 | 2 Palletsprojects, Redhat | 4 Werkzeug, Ceph Storage, Openshift Ironic and 1 more | 2025-02-13 | 8 High |
Werkzeug is a comprehensive WSGI web application library. If an upload of a file that starts with CR or LF and then is followed by megabytes of data without these characters: all of these bytes are appended chunk by chunk into internal bytearray and lookup for boundary is performed on growing buffer. This allows an attacker to cause a denial of service by sending crafted multipart data to an endpoint that will parse it. The amount of CPU time required can block worker processes from handling legitimate requests. This vulnerability has been patched in version 3.0.1. | ||||
CVE-2023-46118 | 2 Redhat, Vmware | 2 Openstack, Rabbitmq | 2025-02-13 | 4.9 Medium |
RabbitMQ is a multi-protocol messaging and streaming broker. HTTP API did not enforce an HTTP request body limit, making it vulnerable for denial of service (DoS) attacks with very large messages. An authenticated user with sufficient credentials can publish a very large messages over the HTTP API and cause target node to be terminated by an "out-of-memory killer"-like mechanism. This vulnerability has been patched in versions 3.11.24 and 3.12.7. | ||||
CVE-2023-45288 | 3 Go Standard Library, Golang, Redhat | 33 Net\/http, Http2, Acm and 30 more | 2025-02-13 | 7.5 High |
An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no memory is allocated to store the excess headers, but they are still parsed. This permits an attacker to cause an HTTP/2 endpoint to read arbitrary amounts of header data, all associated with a request which is going to be rejected. These headers can include Huffman-encoded data which is significantly more expensive for the receiver to decode than for an attacker to send. The fix sets a limit on the amount of excess header frames we will process before closing a connection. | ||||
CVE-2023-45287 | 2 Golang, Redhat | 11 Go, Enterprise Linux, Migration Toolkit Applications and 8 more | 2025-02-13 | 7.5 High |
Before Go 1.20, the RSA based TLS key exchanges used the math/big library, which is not constant time. RSA blinding was applied to prevent timing attacks, but analysis shows this may not have been fully effective. In particular it appears as if the removal of PKCS#1 padding may leak timing information, which in turn could be used to recover session key bits. In Go 1.20, the crypto/tls library switched to a fully constant time RSA implementation, which we do not believe exhibits any timing side channels. | ||||
CVE-2023-43804 | 4 Debian, Fedoraproject, Python and 1 more | 12 Debian Linux, Fedora, Urllib3 and 9 more | 2025-02-13 | 5.9 Medium |
urllib3 is a user-friendly HTTP client library for Python. urllib3 doesn't treat the `Cookie` HTTP header special or provide any helpers for managing cookies over HTTP, that is the responsibility of the user. However, it is possible for a user to specify a `Cookie` header and unknowingly leak information via HTTP redirects to a different origin if that user doesn't disable redirects explicitly. This issue has been patched in urllib3 version 1.26.17 or 2.0.5. | ||||
CVE-2023-39326 | 2 Golang, Redhat | 20 Go, Ansible Automation Platform, Cryostat and 17 more | 2025-02-13 | 5.3 Medium |
A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response body to read many more bytes from the network than are in the body. A malicious HTTP client can further exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature which permit including additional metadata in a request or response body sent using the chunked encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by inserting a large metadata segment with each byte transferred. The chunk reader now produces an error if the ratio of real body to encoded bytes grows too small. | ||||
CVE-2023-39325 | 4 Fedoraproject, Golang, Netapp and 1 more | 53 Fedora, Go, Http2 and 50 more | 2025-02-13 | 7.5 High |
A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the attacker to create a new request while the existing one is still executing. With the fix applied, HTTP/2 servers now bound the number of simultaneously executing handler goroutines to the stream concurrency limit (MaxConcurrentStreams). New requests arriving when at the limit (which can only happen after the client has reset an existing, in-flight request) will be queued until a handler exits. If the request queue grows too large, the server will terminate the connection. This issue is also fixed in golang.org/x/net/http2 for users manually configuring HTTP/2. The default stream concurrency limit is 250 streams (requests) per HTTP/2 connection. This value may be adjusted using the golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams setting and the ConfigureServer function. | ||||
CVE-2023-39322 | 3 Go Standard Library, Golang, Redhat | 18 Crypto Tls, Go, Acm and 15 more | 2025-02-13 | 7.5 High |
QUIC connections do not set an upper bound on the amount of data buffered when reading post-handshake messages, allowing a malicious QUIC connection to cause unbounded memory growth. With fix, connections now consistently reject messages larger than 65KiB in size. | ||||
CVE-2023-39321 | 2 Golang, Redhat | 17 Go, Acm, Ansible Automation Platform and 14 more | 2025-02-13 | 7.5 High |
Processing an incomplete post-handshake message for a QUIC connection can cause a panic. |
