Astra Linux – Vulnerability in Firefox

The NSCDeriveKey function inadvertently assumed that the phKey parameter was always non-NULL. When the parameter was passed as NULL, a segmentation fault occurred, resulting in crashes. This behavior conflicts with the PKCS11 v3.0 specification, which allows phKey to be NULL for certain mechanism...

Astra Linux – Vulnerability in opensc

A vulnerability was discovered in OpenSC, OpenSC tools, the PKCS11 module, minidrivers, and CTK. The issue arises from the lack of initialization of variables that should be initialized as arguments to other functions, etc...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: “fou”: fixed the initialization of “grc”. “grc” must be initialized first. There may be a situation where if “fou” is NULL, “goto out” will be executed, and “grc” will be used in an uninitialized state...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: ipv6: prevented possible UAF in ip6xmit If skbexpandhead returns NULL, the skb has been freed, and the associated dst/idev may also have been freed. We must use rcureadlock to prevent possible UAF...

Astra Linux – Vulnerability in Firefox, Thunderbird

An attacker could, through a specially crafted multipart response, execute arbitrary JavaScript under the resource://pdf.js origin. This would allow them to access PDF content from other origins. This access is limited to “same site” documents due to the Site Isolation feature on desktop clients,...

Astra Linux – Vulnerability in Firefox

Memory safety bugs exist in Firefox 134 and Thunderbird 134. 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 has been fixed in Firefox 135 and Thunderbird...

Astra Linux – Vulnerability in linux-astra-modules-6.1

The vulnerability of the parsecsecid and pscsecidtolbl functions in Linux Astra Modules is related to errors during thread blocking. Exploiting this vulnerability allows a perpetrator to cause service failures...

Astra Linux – Vulnerability in PHP 8.2

In PHP versions 8.1. before 8.1.31, 8.2. before 8.2.26, and 8.3. before 8.3.14, uncontrolled long string inputs to the ldapescape function on 32-bit systems can lead to an integer overflow, resulting in an out-of-bounds write...

Astra Linux – Vulnerability in Qemu

A heap buffer overflow was detected in the virtio-snd device in QEMU. When reading input audio through the virtio-snd input callback, the virtiosndpcmincb function did not check whether the allocated I/O block could accommodate the data buffer. This issue can lead to an out-of-bounds write if the...
