Code execution via query method out-of-bounds read
Published Jul 15, 2022 · Updated Apr 23, 2025
Out-of-bounds read in Adobe Acrobat Reader allows remote attackers to execute code after a user opens a crafted PDF file. The query method processes attacker-controlled JavaScript actions by reading past the end of an allocated object. Affected Reader releases include the Continuous, 2020, and 2017 tracks on Windows and macOS; exploitation requires user interaction and runs code in the current user's process.
