Description
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.

Executive Summary

This vulnerability is a heap-buffer-overflow in the rastertopclx filter of cups-filters version 2.0.1 and earlier. When processing specially crafted malicious input data, the program crashes with a segmentation fault. This memory corruption issue can potentially allow an attacker to execute arbitrary code.

Impact Analysis

The vulnerability can cause the cups-filters program to crash and may allow an attacker to execute arbitrary code on the affected system, which could lead to unauthorized actions or system compromise.

Mitigation Strategies

Update cups-filters to a version later than 2.0.1 where the vulnerability has been patched (commit 956283c). Avoid processing untrusted or malicious input data with the rastertopclx filter until the update is applied.
