How to fix?

Upgrade Debian:10 glib2.0 to version 2.58.3-2+deb10u3 or higher.

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 Debian. See How to fix? for Debian:10 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.
