Information disclosure via ADBC object overread
Published Jul 18, 2022 · Updated Apr 29, 2025
Out-of-bounds read in Foxit PDF Reader 11.2.1.53537 allows remote attackers to disclose process memory via crafted JavaScript. The ADBC newConnection handler fails to validate object allocation boundaries before JavaScript actions read past an allocated object's end. Exploitation requires the target to visit a malicious page or open a malicious file; the disclosure can support a separate exploit chain but does not itself alter data or interrupt the application.
