Memory disclosure via out-of-bounds parser read
Published May 11, 2022 · Updated Sep 17, 2024
Out-of-bounds read in affected Adobe Acrobat Reader versions allows attackers to disclose process memory through a crafted PDF. The file parser reads beyond an allocated memory structure while processing malformed content; Adobe has not disclosed the affected routine or field. Exploitation requires user interaction: a local user must open the malicious file, and the disclosed memory can aid an ASLR bypass.
