CVE-2024-13050

Code execution via unchecked VC6 data length

Published Dec 30, 2024 · Updated Dec 30, 2024

Heap-based buffer overflow in Ashlar-Vellum Graphite 13 SE build 13.0.48 allows remote attackers to execute code via a crafted VC6 file. The VC6 parser copies attacker-controlled data into a heap buffer without first validating its declared length. Exploitation requires a user to visit a malicious page or open the file, and resulting code runs in the current application process.
