Memory disclosure
Published Aug 20, 2021 · Updated Sep 17, 2024
Out-of-bounds reads in affected Adobe Acrobat Reader releases allow attackers to disclose process memory in the current user's context. Adobe has not disclosed the affected parser, file format, or the operation that reads past its intended boundary when the file is processed. Exploitation requires a victim to open the malicious file; the published impact is limited to disclosure, with no integrity or availability effect.
