Astra Linux – Vulnerability in Firefox

Search queries in the default search engine might appear to be the currently navigated URL, provided that the search query itself is a properly formed URL. This could lead to a site spoofing another site, if it was maliciously set as the default search engine. This vulnerability affects Firefox...

Astra Linux – Vulnerability in Firefox, Thunderbird

Memory safety bugs exist in Firefox 116, Firefox ESR 115.1, and Thunderbird 115.1. Some of these bugs exhibited signs of memory corruption, and we assume that with sufficient effort, some of these bugs could have been exploited to execute arbitrary code. This vulnerability affects Firefox version...

Astra Linux – Vulnerability in gnupg1

Libgcrypt before version 1.7.8 is vulnerable to a cache-side-channel attack that can lead to a complete failure of the RSA-1024 algorithm. This attack occurs when the left-to-right method is used for computing the sliding-window expansion. It is believed that the same attack also works on the...

A flaw was discovered in the Linux kernel. A use-after-free occurred in the way the console subsystem utilized ioctls KDGKBSENT and KDSKBSENT. A local user could exploit this flaw to gain access to memory beyond its intended scope. The most significant threat posed by this vulnerability is to dat...

Astra Linux – Vulnerability in Lapack

A out-of-bounds read flaw was discovered in the CLARRV, DLARRV, SLARRV, and ZLARRV functions in lapack, from version 3.10.0 onward. This flaw was also used in OpenBLAS prior to version 0.3.18. Specifically, inputs designed to exploit this flaw could cause applications using lapack to crash or...

Astra Linux – Vulnerability in Linux 5.10, Linux

Several Linux PV device frontends are vulnerable to attacks by backends that use grant table interfaces to remove access rights from resources. This can lead to potential data leaks, data corruption by malicious backends, and denial of service attacks. The backends that use these interfaces may n...

Astra Linux – Vulnerability in Firefox

When a network error occurred during page loading, the previous content could remain visible, accompanied by a blank URL bar. This could be used to disguise a spoofed website. This vulnerability affects Firefox versions earlier than 126...

Astra Linux – Vulnerability in Firefox, Thunderbird

A memory safety bug exists in Firefox 124, Firefox ESR 115.9, and Thunderbird 115.9. This bug exhibited signs of memory corruption, and we assume that with sufficient effort, this could have been exploited to execute arbitrary code. This vulnerability affects Firefox versions less than 125, Firef...
