Pygments is a generic syntax highlighter suitable for use in code hosting, forums, wikis or other applications that need to prettify source code.
A vulnerability in FontManager’s _get_nix_font_path function allows shell metacharacters to be passed in a font name.
A remote attacker could possibly execute arbitrary code with the privileges of the process.
There is no known workaround at this time.
All Pygments users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-python/pygments-2.0.2-r1"
