Astra Linux – Vulnerabilities in Python 2.7, Python 3.11, Python 3.7

There is a defect in the CPython “tarfile” module that affects the “TarFile” extraction and entry enumeration APIs. The tar implementation processes tar archives with negative offsets without errors, which can lead to an infinite loop and deadlock during the parsing of maliciously crafted tar...

Astra Linux – Vulnerability in node-cipher-base

There is a vulnerability in improper input validation in the cipher-base module, which allows for manipulation of input data. This issue affects cipher-base version 1.0.4...

Astra Linux – Vulnerability in python-setuptools

A vulnerability exists in the packageindex module of pypa/setuptools versions up to 69.1.1, allowing for remote code execution through its download functions. These functions, which are used to download packages from URLs provided by users or retrieved from package index servers, are vulnerable t...

Astra Linux – Vulnerability in Intel Microcode

Improper input validation in some IntelR TDX module software prior to version 1.5.05.46.698 may allow a privileged user to potentially enable privilege escalation through local access...

Astra Linux – Vulnerability in gnupg2

GnuPG versions up to 2.3.6 allow for signature forgery in unusual situations where an attacker possesses secret-key information from a victim’s keyring, and other constraints such as the use of GPGME are met. This can be achieved by injecting malicious data into the command line’s status line...

Astra Linux - Vulnerability in Golang-1.19

The go command may execute arbitrary code during compilation when using cgo. This can occur when running “go get” on a malicious module, or when running any other command that compiles unauthorized code. This issue can be triggered by linker flags, specified via the cgo LDFLAGS directive. Flags...

Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system. In versions 2.4.2 and earlier, a heap buffer overflow vulnerability existed, which allowed a remote attacker to launch a Denial-of-Service DoS attack. This vulnerability was present in the formatlogline function. Exploitation of this...

Astra Linux – Vulnerability in libxml2

A issue was discovered in libxml2 before version 2.10.3. When parsing a multi-gigabyte XML document with the XMLPARSEHUGE parser option enabled, several integer counters may overflow. This leads to an attempt to access an array at a negative 2GB offset, typically resulting in a segmentation fault...

Astra Linux – Vulnerability in Apache2

There is a vulnerability in the modproxyftp module of the Apache HTTP Server, known as the “Infinite Loop” condition, which can lead to an infinite loop when using an attacker-controlled FTP server. This issue affects versions 2.4.0 through 2.4.67. Users are recommended to upgrade to version...

Astra Linux – Vulnerability in Qemu

A flaw was discovered in the USB redirector device usb-redir of QEMU. Small USB packets are combined into a single, large transfer request, in order to reduce overhead and improve performance. The combined size of the bulk transfer is used to dynamically allocate a variable length array VLA on th...

Astra Linux – Vulnerability in Python 3.11, Python 3.7

A vulnerability has been identified in the CPython venv module and CLI. This vulnerability arises from improper quoting of path names when creating a virtual environment. As a result, attackers can inject commands into the virtual environment “activation” scripts e.g., using “source...

Astra Linux – Vulnerability in Linux, Linux 5.10

A use-after-free vulnerability was discovered in the rtsxusbmsdrvremove function in the drivers/memstick/host/rtsxusbms.c file within the memstick module of the Linux kernel. In this flaw, a local attacker with user privileges could compromise the confidentiality of system resources. This...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: gpio: mockup: Fixed a NULL pointer dereferencing issue when removing debugfs. We now remove the debugfs entries of the device when unbinding the driver. This now causes a NULL-pointer dereferencing issue at the end of the module,...

Astra Linux – Vulnerability in grub2

A flaw was discovered in grub2. When reading data from a jfs filesystem, grub’s jfs filesystem module uses user-controlled parameters from the filesystem geometry to determine the internal buffer size. However, it improperly checks for integer overflows. A maliciously crafted filesystem may cause...

Astra Linux – Vulnerability in docker.io

Moby is an open-source container framework developed by Docker Inc., distributed as Docker, Mirantis Container Runtime, and various other downstream projects/products. The Moby daemon component, dockerd, which was originally developed as “moby/moby”, is commonly referred to as Docker. Swarm Mode ...

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: ima: Handle error codes returned by imafilterrulematch. In imamatchrules, if imafilterrulematch returns -ENOENT due to the rule being NULL, the function incorrectly skips the 'if !rc' check and sets 'result = true'. The LSM rule ...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: tty: fixed a possible nullptrdefer issue in spkttyiorelease. Run the following tests on the qemu platform: syzkaller: modprobe speakupaudptr input: Speakup as /devices/virtual/input/input4 initialized device: /dev/synth, node...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: LSM: General protection fault in legacyparseparam The usual LSM hook mechanism of “bailing on failure” doesn’t work in cases where a security module returns an error code indicating that it doesn’t recognize an input. In this...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: RDMA/restrack: Fixed potential invalid address access issues. The kernname of the struct rdmarestrackentry was set to KBUILDMODNAME in ibcreatecq. If the module exits but forgets to remove this rdmarestrackentry, it could lead...

Astra Linux – Vulnerability in libxml2

A flaw was discovered in the libxml2 library. This vulnerability arises from uncontrolled resource consumption when processing XML catalogs that contain repeated elements pointing to the same downstream catalog. A remote attacker can exploit this vulnerability by providing malicious catalogs,...
