Information disclosure via JPEG2000 out-of-bounds read
Published Jan 26, 2023 · Updated Apr 1, 2025
Out-of-bounds read in PDF-XChange Editor 9.4.362.0 allows remote attackers to disclose process data through a crafted PDF file. The JPEG2000 parsing path reads beyond an allocated buffer when processing malformed image data embedded in a PDF. Exploitation requires the target to visit a malicious page or open the file; code execution requires chaining with another vulnerability.
