Code execution via unchecked VC6 buffer copy
Published Sep 17, 2025 · Updated Sep 17, 2025
Stack-based buffer overflow in Ashlar-Vellum Graphite 13_SE_13048 allows remote attackers to execute code through a crafted VC6 file. The VC6 parser copies attacker-controlled data into a fixed-size stack buffer without validating its length. Exploitation requires the target to open the file or visit a malicious page, and code runs in the Graphite process context.
