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
-------------------------------------------------------------------
1 dev-python/pygments < 2.0.2-r1 >= 2.0.2-r1
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"
References
==========
