CVE-2024-22562Public exploit

Local crash via stack buffer underflow

Published Jan 19, 2024 · Updated Jun 16, 2025

Stack buffer underflow in SWFTools 0.9.2 allows local users to crash swfc by supplying a crafted script file for processing. During the first parsing pass, dict_foreach_keyvalue reads eight bytes before a stack object while findFontUsage analyzes command arguments. A user must run swfc on attacker-supplied content; the public reproducer demonstrates an AddressSanitizer abort, but no public evidence demonstrates code execution.
