Detailsinfo

A vulnerability was found in OpenPrinting cups-filters up to 2.0.1. It has been declared as problematic. This vulnerability affects an unknown function of the component Cups Printing Service. The manipulation with an unknown input leads to a heap-based overflow vulnerability. The CWE definition for the vulnerability is CWE-122. A heap overflow condition is a buffer overflow, where the buffer that can be overwritten is allocated in the heap portion of memory, generally meaning that the buffer was allocated using a routine such as malloc(). As an impact it is known to affect availability. CVE summarizes:

cups-filters contains backends, filters, and other software required to get the cups printing service working on operating systems other than macos. In versions 2.0.1 and prior, a heap-buffer-overflow vulnerability in the rastertopclx filter causes the program to crash with a segmentation fault when processing maliciously crafted input data. This issue can be exploited to trigger memory corruption, potentially leading to arbitrary code execution. This issue has been patched via commit 956283c.
