Background
pygments is a generic syntax highlighter that is commonly used to add code highlighting functionality to various applications and programming languages. It provides support for a wide range of languages and formats, making it a popular choice among developers. However, a vulnerability has been discovered in pygments that allows remote attackers to execute arbitrary code through a shell injection attack. This vulnerability is caused by the lack of proper input sanitization when processing font names.
Vulnerability Detail
The shell injection vulnerability in pygments allows an attacker to execute arbitrary code by injecting shell metacharacters into a font name. This can be exploited by an attacker who can control the font name parameter, such as in a web application that allows users to specify custom fonts. By injecting malicious shell commands, an attacker can execute arbitrary code with the privileges of the user running the pygments process. This can lead to various consequences, including unauthorized access, data theft, or even complete compromise of the affected system.
