Name of the Vulnerable Software and Affected Versions GLib (affected versions not specified)

Description 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.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
