CVE-2023-4504

Name of the Vulnerable Software and Affected Versions CUPS versions prior to 2.4.7

Description The issue is related to a failure in validating the length provided by an attacker-crafted PPD PostScript document, making CUPS and libppd susceptible to a heap-based buffer overflow and possibly code execution. This can be exploited by an attacker to potentially elevate privileges and execute arbitrary code.

Recommendations For versions prior to 2.4.7, update to CUPS version 2.4.7 or later to resolve the issue. As a temporary workaround, consider restricting the processing of PPD PostScript documents to minimize the risk of exploitation.
