PDF-XChange Editor vulnerability analysis and mitigation

PDF-XChange Editor contains a remote code execution vulnerability (CVE-2024-8825) discovered in its PDF file parsing functionality. The vulnerability was disclosed on November 22, 2024, affecting PDF-XChange Editor version 10.3.0.386 and earlier versions. This security flaw allows remote attackers to execute arbitrary code on affected installations of the software (ZDI Advisory).

The vulnerability stems from an out-of-bounds read condition during PDF file parsing. The specific flaw exists due to the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. The vulnerability has been assigned a CVSS v3.1 base score of 7.8 (HIGH) with the vector string CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (NVD).
