Astra Linux – Vulnerability in xorg-server

A vulnerability was discovered in X.Org. This issue arises due to a dangling pointer in DeepCopyPointerClasses, which can be exploited by ProcXkbSetDeviceInfo and ProcXkbGetDeviceInfo to read from and write to freed memory. This can lead to local privilege escalation on systems where the X server...

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 ...
