Severity:normal
Title:Pygments: Arbitrary code execution
Date:12/04/2016
Bugs: #564478
ID:201612-05

Synopsis

Pygments is vulnerable to remote code execution if an attacker is allowed to specify the font name.

Background

Pygments is a generic syntax highlighter suitable for use in code hosting, forums, wikis or other applications that need to prettify source code.

Affected packages

Package Vulnerable Unaffected Architecture(s)
dev-python/pygments < 2.0.2-r1 >= 2.0.2-r1 All supported architectures

Description

A vulnerability in FontManager’s _get_nix_font_path function allows shell metacharacters to be passed in a font name.

Impact

A remote attacker could possibly execute arbitrary code with the privileges of the process.

Workaround

There is no known workaround at this time.

Resolution

All Pygments users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=dev-python/pygments-2.0.2-r1"
