CVE-2022-48622
Published: 26 January 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.

| mdeslaur | as of 2024-04-15, upstream GdkPixbuf developers have no fix for this issue, and suggest disabling the ANI loader. Ubuntu packages do have the ANI loader enabled. Marking as deferred for now. |
