Code execution via clearTimeOut out-of-bounds write
Published May 3, 2024 · Updated Aug 2, 2024
Out-of-bounds write in app-object handling in Tungsten Automation Power PDF 5.0.0.19 allows remote attackers to execute code via a malicious file. The clearTimeOut handling path fails to validate user-supplied app-object data before writing past the end of an allocated buffer. Exploitation requires the target to open a malicious file or visit a malicious page, and the resulting code runs in the current process.
