| CVE-2018-16888 | 4 Canonical, Netapp, Redhat and 1 more | 6 Ubuntu Linux, Active Iq Performance Analytics Services, Element Software and 3 more | 2024-11-21 | 4.7 Medium |
| It was discovered systemd does not correctly check the content of PIDFile files before using it to kill processes. When a service is run from an unprivileged user (e.g. User field set in the service file), a local attacker who is able to write to the PIDFile of the mentioned service may use this flaw to trick systemd into killing other services and/or privileged processes. Versions before v237 are vulnerable. | ||||
| CVE-2018-16884 | 4 Canonical, Debian, Linux and 1 more | 8 Ubuntu Linux, Debian Linux, Linux Kernel and 5 more | 2024-11-21 | 8.0 High |
| A flaw was found in the Linux kernel's NFS41+ subsystem. NFS41+ shares mounted in different network namespaces at the same time can make bc_svc_process() use wrong back-channel IDs and cause a use-after-free vulnerability. Thus a malicious container user can cause a host kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. | ||||
| CVE-2018-16882 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 8.8 High |
| A use-after-free issue was found in the way the Linux kernel's KVM hypervisor processed posted interrupts when nested(=1) virtualization is enabled. In nested_get_vmcs12_pages(), in case of an error while processing posted interrupt address, it unmaps the 'pi_desc_page' without resetting 'pi_desc' descriptor address, which is later used in pi_test_and_clear_on(). A guest user/process could use this flaw to crash the host kernel resulting in DoS or potentially gain privileged access to a system. Kernel versions before 4.14.91 and before 4.19.13 are vulnerable. | ||||
| CVE-2018-16880 | 2 Canonical, Linux | 2 Ubuntu Linux, Linux Kernel | 2024-11-21 | 7.0 High |
| A flaw was found in the Linux kernel's handle_rx() function in the [vhost_net] driver. A malicious virtual guest, under specific conditions, can trigger an out-of-bounds write in a kmalloc-8 slab on a virtual host which may lead to a kernel memory corruption and a system panic. Due to the nature of the flaw, privilege escalation cannot be fully ruled out. Versions from v4.16 and newer are vulnerable. | ||||
| CVE-2018-16878 | 6 Canonical, Clusterlabs, Debian and 3 more | 9 Ubuntu Linux, Pacemaker, Debian Linux and 6 more | 2024-11-21 | 5.5 Medium |
| A flaw was found in pacemaker up to and including version 2.0.1. An insufficient verification inflicted preference of uncontrolled processes can lead to DoS | ||||
| CVE-2018-16877 | 6 Canonical, Clusterlabs, Debian and 3 more | 9 Ubuntu Linux, Pacemaker, Debian Linux and 6 more | 2024-11-21 | 7.8 High |
| A flaw was found in the way pacemaker's client-server authentication was implemented in versions up to and including 2.0.0. A local attacker could use this flaw, and combine it with other IPC weaknesses, to achieve local privilege escalation. | ||||
| CVE-2018-16876 | 4 Canonical, Debian, Redhat and 1 more | 10 Ubuntu Linux, Debian Linux, Ansible and 7 more | 2024-11-21 | 5.3 Medium |
| ansible before versions 2.5.14, 2.6.11, 2.7.5 is vulnerable to a information disclosure flaw in vvv+ mode with no_log on that can lead to leakage of sensible data. | ||||
| CVE-2018-16872 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2024-11-21 | 5.3 Medium |
| A flaw was found in qemu Media Transfer Protocol (MTP). The code opening files in usb_mtp_get_object and usb_mtp_get_partial_object and directories in usb_mtp_object_readdir doesn't consider that the underlying filesystem may have changed since the time lstat(2) was called in usb_mtp_object_alloc, a classical TOCTTOU problem. An attacker with write access to the host filesystem shared with a guest can use this property to navigate the host filesystem in the context of the QEMU process and read any file the QEMU process has access to. Access to the filesystem may be local or via a network share protocol such as CIFS. | ||||
| CVE-2018-16867 | 3 Canonical, Fedoraproject, Qemu | 3 Ubuntu Linux, Fedora, Qemu | 2024-11-21 | 7.8 High |
| A flaw was found in qemu Media Transfer Protocol (MTP) before version 3.1.0. A path traversal in the in usb_mtp_write_data function in hw/usb/dev-mtp.c due to an improper filename sanitization. When the guest device is mounted in read-write mode, this allows to read/write arbitrary files which may lead do DoS scenario OR possibly lead to code execution on the host. | ||||
| CVE-2018-16862 | 4 Canonical, Debian, Linux and 1 more | 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more | 2024-11-21 | N/A |
| A security flaw was found in the Linux kernel in a way that the cleancache subsystem clears an inode after the final file truncation (removal). The new file created with the same inode may contain leftover pages from cleancache and the old file data instead of the new one. | ||||
| CVE-2018-16851 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-11-21 | 6.5 Medium |
| Samba from version 4.0.0 and before versions 4.7.12, 4.8.7, 4.9.3 is vulnerable to a denial of service. During the processing of an LDAP search before Samba's AD DC returns the LDAP entries to the client, the entries are cached in a single memory object with a maximum size of 256MB. When this size is reached, the Samba process providing the LDAP service will follow the NULL pointer, terminating the process. There is no further vulnerability associated with this issue, merely a denial of service. | ||||
| CVE-2018-16850 | 3 Canonical, Postgresql, Redhat | 4 Ubuntu Linux, Postgresql, Enterprise Linux and 1 more | 2024-11-21 | 9.8 Critical |
| postgresql before versions 11.1, 10.6 is vulnerable to a to SQL injection in pg_upgrade and pg_dump via CREATE TRIGGER ... REFERENCING. Using a purpose-crafted trigger definition, an attacker can cause arbitrary SQL statements to run, with superuser privileges. | ||||
| CVE-2018-16847 | 2 Canonical, Qemu | 2 Ubuntu Linux, Qemu | 2024-11-21 | 7.8 High |
| An OOB heap buffer r/w access issue was found in the NVM Express Controller emulation in QEMU. It could occur in nvme_cmb_ops routines in nvme device. A guest user/process could use this flaw to crash the QEMU process resulting in DoS or potentially run arbitrary code with privileges of the QEMU process. | ||||
| CVE-2018-16846 | 4 Canonical, Debian, Opensuse and 1 more | 6 Ubuntu Linux, Debian Linux, Leap and 3 more | 2024-11-21 | 6.5 Medium |
| It was found in Ceph versions before 13.2.4 that authenticated ceph RGW users can cause a denial of service against OMAPs holding bucket indices. | ||||
| CVE-2018-16845 | 6 Apple, Canonical, Debian and 3 more | 6 Xcode, Ubuntu Linux, Debian Linux and 3 more | 2024-11-21 | 6.1 Medium |
| nginx before versions 1.15.6, 1.14.1 has a vulnerability in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory disclosure by using a specially crafted mp4 file. The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the .mp4. directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module. | ||||
| CVE-2018-16844 | 5 Apple, Canonical, Debian and 2 more | 5 Xcode, Ubuntu Linux, Debian Linux and 2 more | 2024-11-21 | 7.5 High |
| nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive CPU usage. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file. | ||||
| CVE-2018-16843 | 6 Apple, Canonical, Debian and 3 more | 6 Xcode, Ubuntu Linux, Debian Linux and 3 more | 2024-11-21 | 7.5 High |
| nginx before versions 1.15.6 and 1.14.1 has a vulnerability in the implementation of HTTP/2 that can allow for excessive memory consumption. This issue affects nginx compiled with the ngx_http_v2_module (not compiled by default) if the 'http2' option of the 'listen' directive is used in a configuration file. | ||||
| CVE-2018-16842 | 4 Canonical, Debian, Haxx and 1 more | 6 Ubuntu Linux, Debian Linux, Curl and 3 more | 2024-11-21 | N/A |
| Curl versions 7.14.1 through 7.61.1 are vulnerable to a heap-based buffer over-read in the tool_msgs.c:voutf() function that may result in information exposure and denial of service. | ||||
| CVE-2018-16841 | 3 Canonical, Debian, Samba | 3 Ubuntu Linux, Debian Linux, Samba | 2024-11-21 | 6.5 Medium |
| Samba from version 4.3.0 and before versions 4.7.12, 4.8.7 and 4.9.3 are vulnerable to a denial of service. When configured to accept smart-card authentication, Samba's KDC will call talloc_free() twice on the same memory if the principal in a validly signed certificate does not match the principal in the AS-REQ. This is only possible after authentication with a trusted certificate. talloc is robust against further corruption from a double-free with talloc_free() and directly calls abort(), terminating the KDC process. | ||||
| CVE-2018-16839 | 4 Canonical, Debian, Haxx and 1 more | 4 Ubuntu Linux, Debian Linux, Curl and 1 more | 2024-11-21 | N/A |
| Curl versions 7.33.0 through 7.61.1 are vulnerable to a buffer overrun in the SASL authentication code that may lead to denial of service. | ||||
