Overview
Affected versions of this package are vulnerable to Heap-based Buffer Overflow via the CompressData function in the rastertopclx filter. An attacker can cause memory corruption, potentially leading to arbitrary code execution, by providing a specially crafted input through print job parameters, resulting in a heap buffer overflow of the CompressBuf array.
