Description ybuenos 2023-09-12 10:07:17 UTC

Due to failure in validating the length provided by an attacker-crafted CUPS document, CUPS version v2.5b1 and prior, by default, is susceptible 
to a heap-based buffer overflow, and possibly code execution. This CVE appears to be an instance of CWE-122, a heap-based buffer overflow.
