|---|---|---|---|---|
| CVE-2021-3695 | 4 Fedoraproject, Gnu, Netapp and 1 more | 16 Fedora, Grub2, Ontap Select Deploy Administration Utility and 13 more | 2024-11-21 | 4.5 Medium |
| A crafted 16-bit grayscale PNG image may lead to a out-of-bounds write in the heap area. An attacker may take advantage of that to cause heap data corruption or eventually arbitrary code execution and circumvent secure boot protections. This issue has a high complexity to be exploited as an attacker needs to perform some triage over the heap layout to achieve signifcant results, also the values written into the memory are repeated three times in a row making difficult to produce valid payloads. This flaw affects grub2 versions prior grub-2.12. | ||||
| CVE-2021-3690 | 1 Redhat | 14 Camel Quarkus, Enterprise Linux, Fuse and 11 more | 2024-11-21 | 7.5 High |
| A flaw was found in Undertow. A buffer leak on the incoming WebSocket PONG message may lead to memory exhaustion. This flaw allows an attacker to cause a denial of service. The highest threat from this vulnerability is availability. | ||||
| CVE-2021-3682 | 3 Debian, Qemu, Redhat | 4 Debian Linux, Qemu, Advanced Virtualization and 1 more | 2024-11-21 | 8.5 High |
| A flaw was found in the USB redirector device emulation of QEMU in versions prior to 6.1.0-rc2. It occurs when dropping packets during a bulk transfer from a SPICE client due to the packet queue being full. A malicious SPICE client could use this flaw to make QEMU call free() with faked heap chunk metadata, resulting in a crash of QEMU or potential code execution with the privileges of the QEMU process on the host. | ||||
| CVE-2021-3679 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-11-21 | 5.5 Medium |
| A lack of CPU resource in the Linux kernel tracing module functionality in versions prior to 5.14-rc3 was found in the way user uses trace ring buffer in a specific way. Only privileged local users (with CAP_SYS_ADMIN capability) could use this flaw to starve the resources causing denial of service. | ||||
| CVE-2021-3677 | 3 Fedoraproject, Postgresql, Redhat | 9 Fedora, Postgresql, Enterprise Linux and 6 more | 2024-11-21 | 6.5 Medium |
| A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting. | ||||
| CVE-2021-3672 | 6 C-ares Project, Fedoraproject, Nodejs and 3 more | 19 C-ares, Fedora, Node.js and 16 more | 2024-11-21 | 5.6 Medium |
| A flaw was found in c-ares library, where a missing input validation check of host names returned by DNS (Domain Name Servers) can lead to output of wrong hostnames which might potentially lead to Domain Hijacking. The highest threat from this vulnerability is to confidentiality and integrity as well as system availability. | ||||
| CVE-2021-3669 | 5 Debian, Fedoraproject, Ibm and 2 more | 24 Debian Linux, Fedora, Spectrum Copy Data Management and 21 more | 2024-11-21 | 5.5 Medium |
| A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS. | ||||
| CVE-2021-3660 | 2 Cockpit-project, Redhat | 2 Cockpit, Enterprise Linux | 2024-11-21 | 4.3 Medium |
| Cockpit (and its plugins) do not seem to protect itself against clickjacking. It is possible to render a page from a cockpit server via another website, inside an <iFrame> HTML entry. This may be used by a malicious website in clickjacking or similar attacks. | ||||
| CVE-2021-3659 | 3 Fedoraproject, Linux, Redhat | 17 Fedora, Linux Kernel, Codeready Linux Builder and 14 more | 2024-11-21 | 5.5 Medium |
| A NULL pointer dereference flaw was found in the Linux kernel’s IEEE 802.15.4 wireless networking subsystem in the way the user closes the LR-WPAN connection. This flaw allows a local user to crash the system. The highest threat from this vulnerability is to system availability. | ||||
| CVE-2021-3657 | 4 Debian, Fedoraproject, Isync Project and 1 more | 4 Debian Linux, Fedora, Isync and 1 more | 2024-11-21 | 9.8 Critical |
| A flaw was found in mbsync versions prior to 1.4.4. Due to inadequate handling of extremely large (>=2GiB) IMAP literals, malicious or compromised IMAP servers, and hypothetically even external email senders, could cause several different buffer overflows, which could conceivably be exploited for remote code execution. | ||||
| CVE-2021-3656 | 3 Fedoraproject, Linux, Redhat | 31 Fedora, Linux Kernel, 3scale Api Management and 28 more | 2024-11-21 | 8.8 High |
| A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "virt_ext" field, this issue could allow a malicious L1 to disable both VMLOAD/VMSAVE intercepts and VLS (Virtual VMLOAD/VMSAVE) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. | ||||
| CVE-2021-3655 | 3 Debian, Linux, Redhat | 3 Debian Linux, Linux Kernel, Enterprise Linux | 2024-11-21 | 3.3 Low |
| A vulnerability was found in the Linux kernel in versions prior to v5.14-rc1. Missing size validations on inbound SCTP packets may allow the kernel to read uninitialized memory. | ||||
| CVE-2021-3653 | 3 Debian, Linux, Redhat | 8 Debian Linux, Linux Kernel, Enterprise Linux and 5 more | 2024-11-21 | 8.8 High |
| A flaw was found in the KVM's AMD code for supporting SVM nested virtualization. The flaw occurs when processing the VMCB (virtual machine control block) provided by the L1 guest to spawn/handle a nested guest (L2). Due to improper validation of the "int_ctl" field, this issue could allow a malicious L1 to enable AVIC support (Advanced Virtual Interrupt Controller) for the L2 guest. As a result, the L2 guest would be allowed to read/write physical pages of the host, resulting in a crash of the entire system, leak of sensitive data or potential guest-to-host escape. This flaw affects Linux kernel versions prior to 5.14-rc7. | ||||
| CVE-2021-3652 | 2 Port389, Redhat | 4 389-ds-base, Directory Server, Enterprise Linux and 1 more | 2024-11-21 | 6.5 Medium |
| A flaw was found in 389-ds-base. If an asterisk is imported as password hashes, either accidentally or maliciously, then instead of being inactive, any password will successfully match during authentication. This flaw allows an attacker to successfully authenticate as a user whose password was disabled. | ||||
| CVE-2021-3640 | 6 Canonical, Debian, Fedoraproject and 3 more | 23 Ubuntu Linux, Debian Linux, Fedora and 20 more | 2024-11-21 | 7.0 High |
| A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system. | ||||
| CVE-2021-3639 | 2 Redhat, Uninett | 2 Enterprise Linux, Mod Auth Mellon | 2024-11-21 | 6.1 Medium |
| A flaw was found in mod_auth_mellon where it does not sanitize logout URLs properly. This issue could be used by an attacker to facilitate phishing attacks by tricking users into visiting a trusted web application URL that redirects to an external and potentially malicious server. The highest threat from this liability is to confidentiality and integrity. | ||||
| CVE-2021-3635 | 3 Fedoraproject, Linux, Redhat | 3 Fedora, Linux Kernel, Enterprise Linux | 2024-11-21 | 4.4 Medium |
| A flaw was found in the Linux kernel netfilter implementation in versions prior to 5.5-rc7. A user with root (CAP_SYS_ADMIN) access is able to panic the system when issuing netfilter netflow commands. | ||||
| CVE-2021-3634 | 6 Debian, Fedoraproject, Libssh and 3 more | 7 Debian Linux, Fedora, Libssh and 4 more | 2024-11-21 | 6.5 Medium |
| A flaw has been found in libssh in versions prior to 0.9.6. The SSH protocol keeps track of two shared secrets during the lifetime of the session. One of them is called secret_hash and the other session_id. Initially, both of them are the same, but after key re-exchange, previous session_id is kept and used as an input to new secret_hash. Historically, both of these buffers had shared length variable, which worked as long as these buffers were same. But the key re-exchange operation can also change the key exchange method, which can be based on hash of different size, eventually creating "secret_hash" of different size than the session_id has. This becomes an issue when the session_id memory is zeroed or when it is used again during second key re-exchange. | ||||
| CVE-2021-3632 | 1 Redhat | 4 Enterprise Linux, Keycloak, Red Hat Single Sign On and 1 more | 2024-11-21 | 7.5 High |
| A flaw was found in Keycloak. This vulnerability allows anyone to register a new security device or key when there is not a device already registered for any user by using the WebAuthn password-less login flow. | ||||
| CVE-2021-3631 | 2 Netapp, Redhat | 5 Ontap Select Deploy Administration Utility, Advanced Virtualization, Enterprise Linux and 2 more | 2024-11-21 | 6.3 Medium |
| A flaw was found in libvirt while it generates SELinux MCS category pairs for VMs' dynamic labels. This flaw allows one exploited guest to access files labeled for another guest, resulting in the breaking out of sVirt confinement. The highest threat from this vulnerability is to confidentiality and integrity. | ||||
