CVE-2021-46829

Status Candidate

Overview

GNOME GdkPixbuf (aka GDK-PixBuf) before 2.42.8 allows a heap-based buffer overflow when compositing or clearing frames in GIF files, as demonstrated by io-gif-animation.c composite_frame. This overflow is controllable and could be abused for code execution, especially on 32-bit systems.
