Astra Linux – Vulnerability in cups

OpenPrinting CUPS is an open-source printing system for Linux and other Unix-like operating systems. In versions 2.4.8 and earlier, when starting the cupsd server with a Listen configuration item pointing to a symbolic link, the cupsd process could perform arbitrary chmod operations on the target...

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 glib2.0

A issue was discovered in GNOME GLib before version 2.66.8. When the gfilereplace function is used with GFILECREATEREPLACEDESTINATION to replace a path that is a dangling symlink, it incorrectly creates the target of the symlink as an empty file. This could potentially have security implications ...

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...
