Memory disclosure via Annotation object over-read
Published May 11, 2022 · Updated Sep 16, 2024
Out-of-bounds read in affected Adobe Acrobat Reader releases allows attackers to disclose process memory through a crafted PDF. JavaScript actions against Annotation objects make Reader access bytes beyond the end of an allocated object. Exploitation requires a victim to visit a malicious page or open the file; the disclosure can reveal data useful for bypassing ASLR and chaining code execution.
