Last modified

CVE-2022-48622 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. In GNOME GdkPixbuf (aka gdk-pixbuf) through 2.42.10, the ANI (Windows animated cursor) decoder encounters heap memory corruption (in ani_load_chunk in io-ani.c) when parsing chunks in a crafted .ani file. A crafted file could allow an attacker to overwrite heap metadata, leading to a denial of service or code execution attack. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
