Code execution via malformed JP2 object write
Published May 3, 2024 · Updated Aug 2, 2024
Out-of-bounds write in Tungsten Automation Power PDF 5.0.0.19 allows remote attackers to execute code through a malicious JP2 file. The JP2 parser fails to validate user-supplied data before writing it, so the write extends past the end of an allocated object. Exploitation requires the target to visit a malicious page or open a malicious file, and successful code runs in the context of the current Power PDF process.
