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.

An issue was discovered in GNOME GLib before 2.66.6 and 2.67.x before 2.67.3. The function g_bytes_new has an integer overflow on 64-bit platforms due to an implicit cast from 64 bits to 32 bits. The overflow could potentially lead to memory corruption.
