CVE-2022-28874Network attack vector

Scanning-engine crash via malformed PE32 files

Published May 23, 2022 · Updated Aug 3, 2024

Heap-buffer overflows in F-Secure and WithSecure security products allow remote attackers to crash the scanning engine with PE32 files. The scanning engine corrupts memory and writes beyond heap-buffer boundaries while parsing malformed PE32 input. A crafted file must enter a protected scan path; the resulting process crash interrupts malware scanning, and the vendor reports no known exploitation.
