CVE-2022-48622: Out-of-bounds Write

January 26, 2024 (updated February 2, 2024)

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. This occurs in gdk_pixbuf_set_option() in gdk-pixbuf.c.
