Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

A vulnerability related to out-of-bounds memory access was discovered in the Linux kernel’s XFS file system, regarding how a user restores an XFS image after a failure with a dirty log journal. This vulnerability allows a local user to crash the system or potentially escalate their privileges on...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

A flaw was discovered in the Linux kernel. The tun/tap sockets have their socket UID hardcoded to 0 due to a type confusion in their initialization function. While this will usually be correct, since tuntap devices require CAPNETADMIN, it may not always be the case. For example, a non-root user...

Astra Linux – Vulnerability in Linux, Linux 5.10

A race condition accessing file objects in the Linux kernel OverlayFS subsystem was identified. This occurs when users renames files using OverlayFS in a specific manner. A local user could exploit this flaw to cause the system to crash...

Astra Linux – Vulnerability in Intel Microcode

A observable discrepancy in the RAPL interface of certain Intel processors may allow a privileged user to potentially enable information disclosure through local access...

Astra Linux – Vulnerability in dpdk

A flaw was discovered in dpdk. This flaw allows a malicious vhost-user master to attach an unexpected number of fds as auxiliary data to VHOSTUSERGETINFLIGHTFD / VHOSTUSERSETINFLIGHTFD messages that are not closed by the vhost-user slave. By continuously sending such messages, the malicious...

Astra Linux – Vulnerability in Linux 5.15

A flaw in the NULL Pointer Dereference mechanism within the Linux kernel’s NTFS3 driver function attrpunchhole was identified. A local user could exploit this flaw to crash the system...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In 64-bit versions of the Linux kernel, Copyfromuser does not implement uaccessbeginnospec, which allows a user to bypass the “accessok” check and pass a kernel pointer to copyfromuser. This would enable an attacker to leak sensitive information. We recommend upgrading beyond commit...

Astra Linux – Vulnerability in Chromium

Type confusion in DevTools in Google Chrome prior to 111.0.5563.64 allowed a remote attacker who had compromised the renderer process to potentially exploit heap corruption via a crafted UI interaction. Chromium security severity: Low...

postgresql: PostgreSQL: Arbitrary code execution via integer wraparound in tsvector and tsquery functions

A flaw was found in PostgreSQL. An unprivileged database user can exploit an integer wraparound vulnerability in the tsvector and tsquery data type functions. By providing crafted large inputs, the server can be forced to undersize an allocation, leading to an out-of-bounds write. This could...

postgresql-fuzzystrmatch: PostgreSQL fuzzystrmatch: Arbitrary code execution via integer wraparound

A flaw was found in PostgreSQL fuzzystrmatch. A low-privileged database user can exploit an integer wraparound vulnerability by providing extreme inputs to the levenshtein or levenshteinlessequal SQL functions. This allows the user to execute arbitrary code as the operating system user running th...
