CVE-2025-13601: Glib: integer overflow in in g_escape_uri_string()

Description

A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable characters (which would need escaping), the calculation of the length of the escaped string could overflow, leading to a potential write off the end of the newly allocated string.

How to fix

Upgrade to a fixed version: GNOME GLib 2.86.3. Check the vendor advisory for mitigations.
