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

In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: cfg80211: The PMK parameter is now passed as binary data, rather than hexadecimal data. It appears that the hexadecimal passphrase mechanism does not work on newer chips/firmwares e.g., BCM4387. There was actually...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in GNU Binutils 2.32. There is a heap-based buffer over-read in bfddoprnt in bfd.c, due to elfobjectp in elfcode.h mishandling an eshstrndx section of type SHTGROUP by omitting a trailing \0...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in GNU Binutils 2.31. An invalid memory access exists in the bfdstabsectionfindnearestline function in syms.c. Attackers could exploit this vulnerability to cause a denial of service application...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in the GNU Binutils through version 2.31. There is an integer overflow and an infinite loop caused by the ISCONTAINEDBYLMA macro in elf.c...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in GNU Binutils 2.32. It is an out-of-bounds read that leads to a segmentation fault in bfdgetl32 in libbfd.c, when called from pex64getruntimefunction in pei-x8664.c...

Astra Linux – Vulnerability in libgsf

There is an integer overflow vulnerability in the Compound Document Binary File format parser of v1.14.52 in the GNOME Project’s G Structured File Library libgsf. A specially crafted file can lead to an integer overflow, allowing for a heap-based buffer overflow when processing the sector...

Astra Linux – Vulnerability in isc-dhcp

In ISC DHCP 4.1-ESV-R1 - 4.1-ESV-R16, ISC DHCP 4.4.0 - 4.4.2 Other branches of ISC DHCP e.g., releases in the 4.0.x series or earlier, and releases in the 4.3.x series are beyond their End-of-Life period and are no longer supported by ISC. It is clear that this defect is also present in releases...

Astra Linux – Vulnerability in qtbase-opensource-src

In Qt 5.9.x through 5.15.x before 5.15.9, and 6.x before 6.2.4 on Linux and UNIX, QProcess could execute a binary from the current working directory when it was not found in the PATH...

Astra Linux – Vulnerability in Linux 5.10, Linux

In the Linux kernel, the following vulnerability has been resolved: ALSA: seq: Fixed a mismatch in the function prototype in sndseqexpandvarevent. With Clang’s Kernel Control Flow Integrity kCFI, CONFIGCFICLANG, indirect call targets are validated against the expected function pointer prototype t...

Astra Linux – Vulnerability in Systemd

It was discovered that a Systemd service that uses the DynamicUser property can create a SUID/SGID binary that will be allowed to run as the transient service’s UID/GID even after the service is terminated. A local attacker could exploit this flaw to access resources that will be owned by a...

Astra Linux – Vulnerability in glibc

NSCD: Stack-based buffer overflow in netgroup cache If the fixed-size cache of the Name Service Cache Daemon nscd is exhausted due to client requests, then a subsequent client request for netgroup data may lead to a stack-based buffer overflow. This flaw was introduced in glibc 2.15 when the cach...

Astra Linux – Vulnerability in glibc

NSCD: The NetGroup Cache may terminate the daemon due to a memory allocation failure. The NetGroup Cache Daemon’s NSCD netgroup cache uses xmalloc or xrealloc, and these functions may terminate the process due to a memory allocation failure, resulting in a denial of service for clients. This flaw...

Astra Linux – Vulnerability in binutils

A issue was discovered in the Binary File Descriptor BFD library also known as libbfd, as distributed in GNU Binutils 2.32. It involves an attempt at excessive memory allocation in the bfdelfslurpversiontables function within elf.c...

Astra Linux – Vulnerability in node-babel

Babel is a compiler for writing JavaScript code. In @babel/traverse prior to versions 7.23.2 and 8.0.0-alpha.4, as well as all versions of babel-traverse, using Babel to compile code that was specifically crafted by an attacker can lead to arbitrary code execution during compilation, especially...

Astra Linux – Vulnerability in binutils

There is a memory leak issue in the Binary File Descriptor BFD library also known as libbfd within the GNU Binutils 2.34, specifically in the bfdhashlookup function. This issue can lead to a denial of service attack through a specially crafted file...

Astra Linux – Vulnerability in Python 3.7

A flaw was discovered in Python. In algorithms with quadratic time complexity that use non-binary bases, when using int“text”, a system may take 50 milliseconds to parse an int string with 100,000 digits, and 5 seconds for strings with 1,000,000 digits. Functions like float, decimal, int.frombyte...

Astra Linux – Vulnerability in ntfs-3g

A buffer overflow was discovered in NTFS-3G before October 3, 2022. Metadata created within an NTFS image can lead to code execution. A local attacker can exploit this vulnerability if the ntfs-3g binary has the setuid root privilege. An attacker who is physically nearby can also exploit this...

Astra Linux – Vulnerability in Redis

Redis is an in-memory database that persists data on disk. A vulnerability exists starting from version 2.2, and is related to out-of-bounds reads and integer overflow leading to buffer overflow. This vulnerability is present in versions 5.0.13, 6.0.15, and 6.2.5. On 32-bit systems, the Redis BIT...

Astra Linux – Vulnerability in glibc

The Name Service Cache Daemon’s nscd netgroup cache can corrupt memory when the NSS callback does not store all strings in the provided buffer. This flaw was introduced in glibc 2.15, when the cache was added to nscd. This vulnerability only exists in the nscd binary...
