TITLE

GNOME GLib  Vulnerability in conversion between numeric types in

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. GNOME GLib Is vulnerable to a conversion error between numeric types.Denial of service (DoS) It may be put into a state. Currently there is no information about this vulnerability. Please keep an eye on CNNVD or manufacturer announcements.
