CVE-2022-43359Public exploit

Process crash via unchecked LZW table indices

Published Nov 7, 2022 · Updated May 5, 2025

Out-of-bounds read in Gifdec commit 1dcbae19363597314f6623010cc80abad4e47f7c allows local users to crash a process via a crafted GIF file. read_image_data indexes its LZW entry table without first ensuring that the decoded key and entry prefix are below the table entry count. Processing an attacker-supplied image is required; the public reproducer demonstrates a SIGSEGV, while no code execution or data disclosure is documented.
