CVE-2022-27811: 
NixOS vulnerability analysis and mitigation

Overview

GNOME OCRFeeder before version 0.8.4 contains a critical security vulnerability that allows OS command injection through shell metacharacters in PDF or image filenames (NVD). The vulnerability was disclosed on March 23, 2022, and affects all versions of the software prior to the security patch (CISA).

Technical details

The vulnerability allows attackers to inject operating system commands via specially crafted PDF or image filenames containing shell metacharacters. When processing these files, OCRFeeder fails to properly sanitize the input, leading to potential command execution on the target system (NVD).

Impact

If successfully exploited, this vulnerability could allow an attacker to execute arbitrary commands on the affected system with the privileges of the user running OCRFeeder. This could potentially lead to unauthorized access, data theft, or system compromise (NVD).

Mitigation and workarounds

Users are advised to upgrade to OCRFeeder version 0.8.4 or later, which contains the security fix for this vulnerability. If immediate upgrade is not possible, users should exercise caution when processing files from untrusted sources (NVD).
