CVE-2022-48622Public exploit

Code execution via repeated ANI header

Published Jan 26, 2024 · Updated Aug 26, 2024

Out-of-bounds write in GNOME GdkPixbuf 2.42.10 and earlier allows attackers to execute code via a crafted ANI file. The ANI loader's ani_load_chunk function accepts a second anih header and reinitializes animation state that is expected to be initialized once, corrupting heap metadata. An application must process the malicious cursor, requiring user interaction; successful corruption can crash that process or execute code in its security context.
