CVE-2021-46829 is a heap-based buffer overflow vulnerability in GNOME GdkPixbuf versions prior to 2.42.8, specifically affecting the handling of GIF files during frame compositing or clearing. This flaw impacts various distributions including Debian and Fedora, as well as the Gdk-Pixbuf component itself. With a CVSS score of 7.8 (High), it can be triggered by a local attacker through user interaction (e.g., opening a malicious GIF), potentially leading to arbitrary code execution, especially on 32-bit systems. Despite its high severity, there is currently no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
