NVD Description

Note: Versions mentioned in the description apply only to the upstream glib2.0 package and not the glib2.0 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

A flaw was found in how GLib’s GString manages memory when adding data to strings. If a string is already very large, combining it with more input can cause a hidden overflow in the size calculation. This makes the system think it has enough memory when it doesn’t. As a result, data may be written past the end of the allocated memory, leading to crashes or memory corruption.
