Mageia 9: glib2.0 Important Memory Overflow Issue CVE-2025-6052

mageia
Calendar Grey August 2, 2025
Dist Mageia Esm H88
A critical heap overflow vulnerability in Mageia's GLib could result in severe data loss and application failure. Please implement the update without delay.
A flaw was found in how GLib’s GString manages memory when adding data to strings

Summary

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.
