NVD Description

Note: Versions mentioned in the description apply only to the upstream glib2 package and not the glib2 package as distributed by AlmaLinux. See How to fix? for AlmaLinux:10 relevant fixed versions and status.

A flaw was found in GLib. The D-Bus client-side implementation of the DBUS_COOKIE_SHA1 SASL authentication mechanism does not validate the cookie_context parameter received from the server. A malicious D-Bus server can supply a cookie_context containing path traversal sequences, causing the client to read an arbitrary file and exfiltrate sensitive data by verifying guessed file contents against a generated hash.
