CVE-2024-27341

Code execution via unchecked PDF buffer copy

Published Apr 3, 2024 · Updated Aug 2, 2024

Heap-based buffer overflow in Tungsten Automation Power PDF 5.0.0.19 and 5.0.0.57 allows remote attackers to execute code via a crafted PDF. The PDF parser copies user-supplied data into a fixed-length heap buffer without first validating that the data length fits the destination. Exploitation requires the target to open a malicious file or visit a malicious page, and successful exploitation runs code in the current process context.
