Memory disclosure via crafted PostScript processing
Published Aug 11, 2022 · Updated Apr 23, 2025
Improper input validation in Adobe Acrobat Reader allows attackers to disclose sensitive memory through a crafted PostScript file. Acrobat Distiller processes attacker-controlled PostScript without adequate validation, exposing process-memory contents; the exact faulty operation is not public. Exploitation requires a victim to open the file, and disclosed address data can assist an ASLR bypass.
