TITLE

Red Hat Security Advisory 2021-4526-03

DESCRIPTION

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. Currently there is no information about this vulnerability. Please keep an eye on CNNVD or manufacturer announcements. 8) - noarch 3. The following packages have been upgraded to a later upstream version: mingw-glib2 (2.66.7).
