Doc Text:
A flaw was found in GNOME's GdkPixbuf library, a library used to load image data in various formats used by GDK for handling graphical assets. This issue occurs when loading a crafted ANI (animated cursor file) file, which may lead to a heap based out-of-bounds write, causing memory corruption. When a successful attack is in place, it can lead to a denial of service or in some cases arbitrary code execution.

Description Marco Benatto 2024-01-26 18:45:47 UTC
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.
