CVE-2022-28267

Information disclosure via annotation out-of-bounds read

Published May 11, 2022 · Updated Sep 16, 2024

Out-of-bounds read in Adobe Acrobat Reader DC allows remote attackers to disclose sensitive memory via a crafted file. The Annotation object handler reads past an allocated object boundary when processing attacker-controlled document content, exposing data that can help bypass mitigations such as ASLR. Exploitation requires a victim to open the malicious file, and the documented impact is memory disclosure rather than direct code execution.
