CVE-2024-5875

Code execution via unchecked SHP buffer write

Published Nov 22, 2024 · Updated Nov 22, 2024

Out-of-bounds write in IrfanView 4.67 64-bit allows remote attackers to execute code through a crafted SHP file opened by a user. The SHP parser fails to validate user-supplied data before writing it beyond the end of an allocated buffer. Exploitation requires a user to visit a malicious page or open a malicious file, and resulting code runs in the current process.
