CVE-2023-44433

Information disclosure via Annotation buffer over-read

Published May 3, 2024 · Updated Sep 18, 2024

Out-of-bounds read in Annotation handling in Tungsten Automation Power PDF before 5.0.0.15 allows remote attackers to disclose process memory. The AcroForm Annotation parser fails to validate user-supplied data before reading beyond an allocated buffer. Exploitation requires a target to visit a malicious page or open a malicious file, and the disclosed data can support a separate code-execution exploit.
