Memory disclosure via crafted-file out-of-bounds read
Published Apr 15, 2021 · Updated Apr 23, 2025
Out-of-bounds read in Adobe Bridge 10.1.1 and 11.0.1 and earlier allows attackers to disclose process memory via a crafted file. The file parser reads beyond an allocated buffer while processing attacker-controlled file data; Adobe has not identified the parser or faulty read operation. Exploitation requires a victim to open the malicious file, and disclosure is limited to memory available in the current user's process context.
