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 Echo. See How to fix? for Echo:latest relevant fixed versions and status.

A flaw was found in GLib. An integer overflow vulnerability in its Unicode case conversion implementation can lead to memory corruption. By processing specially crafted and extremely large Unicode strings, an attacker could trigger an undersized memory allocation, resulting in out-of-bounds writes. This could cause applications utilizing GLib for string conversion to crash or become unstable.
