Astra Linux – Vulnerability in php-pear

In ArchiveTar version 1.4.11, the Tar.php script allows write operations involving directory traversal, due to insufficient checking of symbolic links. This issue is related to CVE-2020-28948...

Astra Linux – Vulnerability in multipath-tools

Multipath-tools versions 0.7.7 through 0.9.x, prior to 0.9.2, allowed local users to obtain root access. This vulnerability was exploited in conjunction with CVE-2022-41974. Local users who had access to /dev/shm could modify symlinks within multipathd due to incorrect symlink handling. This coul...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerability has been resolved: udf: Fixed NULL pointer dereferencing in the udfsymlink function. In the udfsymlink function, epos.bh is assigned the value returned by udftgetblk. The udftgetblk function is defined in udf/misc.c and returns the value of the...

Astra Linux – Vulnerability in unbound

Unbound from NLnet Labs, including versions up to and including 1.12.0, and NSD from NLnet Labs, including versions up to and including 4.3.3, contain a local vulnerability that allows for a local symlink attack. When creating the PID file, Unbound and NSD either create the file if it does not...

Astra Linux – Vulnerability in Firefox, Thunderbird

When resolving a symbolic link such as file:///proc/self/fd/1, an error message may be generated if the symbolic link resolves to a string containing uninitialized memory in the buffer. This bug only affects Thunderbird on Unix-based operating systems Android, Linux, MacOS. Windows is unaffected...

Astra Linux – Vulnerability in oddjob

A race condition was identified in the mkhomedir tool included with the oddjob package in versions prior to 0.34.5 and 0.34.6. During the home creation process, mkhomedir copies the /etc/skel directory into the newly created home directory and changes its ownership to the home’s user, without...

Astra Linux – Vulnerability in node-tar

The npm package “tar” also known as node-tar in versions prior to 4.4.16, 5.0.8, and 6.1.7 has vulnerabilities related to arbitrary file creation/overwriting and arbitrary code execution. node-tar aims to ensure that any file whose location would be modified by a symbolic link is not extracted...

Astra Linux – Vulnerability in php-pear

In ArchiveTar before version 1.4.14, symlinks can reference targets outside of the extracted archive. This is a separate vulnerability from CVE-2020-36193...

Astra Linux – Vulnerability in sshfs-fuse

SSHFS is a network filesystem client for connecting to SSH servers. Prior to version 3.7.6, a rogue SFTP server could return absolute symlink targets or relative targets containing parent-directory components, which SSHFS would pass through FUSE for resolution by the client kernel against the loc...

Astra Linux – Vulnerability in Firefox

Uploading files that contain symlinks may have allowed an attacker to trick a user into submitting sensitive data to a malicious website. This vulnerability affects Firefox 115...

Astra Linux – Vulnerability in Golang-glog

When logs are written to a widely-writable directory the default, an unprivileged attacker may predict the log file path of a privileged process and pre-create a symbolic link to a sensitive file in its place. When that privileged process runs, it will follow the created symbolic link and overwri...

Astra Linux – Vulnerability in Python 3.11

It allows the extraction filter to be ignored, enabling symlink targets to point outside the destination directory, and modifying some file metadata. This vulnerability affects users who use the TarFile module to extract untrusted tar archives using TarFile.extractall or TarFile.extract, with the...

Astra Linux – Vulnerability in RustC

Rust is a multi-paradigm, general-purpose programming language designed for performance and safety, especially safe concurrency. The Rust Security Response WG was notified that the std::fs::removedirall standard library function is vulnerable due to a race condition that enables symlink creation...

Astra Linux – Vulnerability in sudo

The “sudoedit” personality of Sudo before version 1.9.5 might allow a local unprivileged user to perform arbitrary directory existence tests by exploiting a race condition in the “sudoedit.c” code, which allows a user-controlled directory to be replaced with a symlink pointing to an arbitrary pat...

Astra Linux – Vulnerability in avahi

The avahi-daemon-check-dns.sh script within the Debian avahi package, as of version 0.8-4, is executed as the root user via /etc/network/if-up.d/avahi-daemon. This script allows a local attacker to cause a denial of service or create arbitrary empty files through a symlink attack on files located...

Astra Linux – Vulnerability in open-vm-tools

A issue was discovered in open-vm-tools 2009.03.18-154848. Local users can bypass the intended access restrictions on mounting shares through a symlink attack that exploits a realpath race condition in mount.vmhgfs also known as hgfsmounter...

Astra Linux – Vulnerability in squashfs-tools

The squashfsopendir function in unsquash-2.c within Squashfs-Tools 4.5 enables Directory Traversal, another vulnerability distinct from CVE-2021-40153. A squashfs filesystem that includes a symbolic link, along with files under the same filename, can cause unsquashfs to first create the symbolic...

Astra Linux – Vulnerability in Ansible

There exists an absolute path traversal attack within the Ansible automation platform. This flaw allows an attacker to create a malicious Ansible role and have the victim execute that role. A symbolic link can be used to overwrite a file that is outside of the extraction path...

Astra Linux – Vulnerability in exim4

Exim 4 before 4.94.2 allowed execution with unnecessary privileges. Since Exim operates as root in the log directory which is owned by a non-root user, a symlink or hard link attack could allow overwriting of critical root-owned files anywhere in the filesystem...
