Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: net: mdio: fixed an undefined behavior in bit shifting for mdiobusregister. Shifting a signed 32-bit value by 31 bits is undefined; therefore, the significant bit was changed to unsigned. The UBSAN warning appears as follows:...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: blk-iocost: Avoid out-of-bounds shifts. UBSAN encounters undefined behavior in blk-iocost, where sometimes iocg-delay is shifted right by a number that is too large, resulting in undefined behavior on some architectures. 186.5565...

Astra Linux – Vulnerability in imagemagick

An integer overflow issue was discovered in ImageMagick’s ExportIndexQuantum function in MagickCore/quantum-export.c. Function calls to GetPixelIndex could result in values that are outside the representable range for ‘unsigned char’. When ImageMagick processes a specially crafted PDF file, this...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick’s MagickCore/statistic.c file. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of type unsigned long. This likely affects the availability of the application, but ...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: ctnetlink: Use netlink policy range checks. Replace manual range and mask validations with netlink policy annotations in ctnetlink code paths. This ensures that netlink core rejects invalid values early and can...

Astra Linux – Vulnerability in Firefox

A vulnerability was identified in Thunderbird, where XPath parsing could trigger undefined behavior due to the lack of null checks during attribute access. This could lead to out-of-bounds read access and, potentially, memory corruption. This vulnerability has been fixed in Firefox 138, Firefox E...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: f2fs: fixed to avoid out-of-bounds access in f2fstruncateinodeblocks syzbot reports an UBSAN issue as follows: ------------ cut here --- UBSAN: Array-index out-of-bounds in fs/f2fs/node.h:381:10 Index 18446744073709550692 is out ...

Astra Linux – Vulnerability in Firefox

The ShmemCharMapHashEntry code was susceptible to potentially undefined behavior by bypassing the move semantics for one of its data members. This vulnerability affects Firefox versions less than 126...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerabilities have been resolved: media: gspca: cpia1: shift-out-of-bounds in setflicker Syzkaller reported the following issue: UBSAN: Shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27; shift exponent 245 is too large for a 32-bit type ‘int’. Whe...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bcache: Fixed the abuse of variable-length arrays in btreeiter. btreeiter is used in two ways: either allocated on the stack with a fixed size MAXBSETS, or from a mempool with a dynamic size based on the specific cache set...

Astra Linux – Vulnerability in ffmpeg5

It was discovered that FFmpeg version n6.1 contains a heap buffer overflow vulnerability in the drawblockrectangle function of libavfilter/vfcodecview.c. This vulnerability allows attackers to cause undefined behavior or a Denial of Service DoS attack through crafted inputs...

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

A flaw was discovered in the Framebuffer Console fbcon within the Linux kernel. When values greater than 32 are provided for font-width and font-height in the fbconsetfont function, due to lack of proper checks, an out-of-bounds situation may occur, resulting in undefined behavior and potentially...

Astra Linux – Vulnerability in imagemagick

In ImageMagick, there are many cases where the alignment of the double type is incorrect. The double type requires 8 bytes of alignment, while the float type requires 4 bytes of alignment. This issue is addressed in the MagickCore/property.c file. Whenever malicious or untrusted input is processe...

Astra Linux – Vulnerability in imagemagick

A floating-point mathematical calculation within the ScaleAnyToQuantum function in /MagickCore/quantum-private.h could lead to undefined behavior, resulting in a value that falls outside the range of the type unsigned long long. This flaw can be triggered by a malicious input file under certain...

Astra Linux – Vulnerability in imagemagick

A flaw was discovered in ImageMagick, specifically in the code file coders/bmp.c. An attacker who submits a crafted file processed by ImageMagick could trigger undefined behavior, resulting in values that are outside the range of the type unsigned int. This likely leads to a disruption in the...
