NVD Description

Note: Versions mentioned in the description apply only to the upstream glib2-devel package and not the glib2-devel package as distributed by RHEL. See How to fix? for RHEL:8 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.
