CVE-2023-39486

Code execution via insufficient JP2 input validation

Published May 3, 2024 · Updated Aug 2, 2024

Memory corruption in PDF-XChange Editor 9.4.364.0 and 10.0.1.371 allows remote attackers to execute code through a crafted JP2 file. The JP2 parser insufficiently validates user-supplied data before processing it, producing a memory-corruption condition. Exploitation requires a user to visit malicious content or open the file, and resulting code runs in the current process.
