========================================================================== Ubuntu Security Notice USN-4897-1 March 30, 2021
pygments vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.10 - Ubuntu 20.04 LTS - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS
Summary:
Pygments could be made to hang if it opened a specially crafted file.
Software Description: - pygments: Generic syntax highlighter
Details:
Ben Caller discovered that Pygments incorrectly handled parsing certain files. If a user or automated system were tricked into parsing a specially crafted file, a remote attacker could cause Pygments to hang or consume resources, resulting in a denial of service.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 20.10: python3-pygments 2.3.1+dfsg-4ubuntu0.2
Ubuntu 20.04 LTS: python-pygments 2.3.1+dfsg-1ubuntu2.2 python3-pygments 2.3.1+dfsg-1ubuntu2.2
Ubuntu 18.04 LTS: python-pygments 2.2.0+dfsg-1ubuntu0.2 python3-pygments 2.2.0+dfsg-1ubuntu0.2
Ubuntu 16.04 LTS: python-pygments 2.1+dfsg-1ubuntu0.2 python3-pygments 2.1+dfsg-1ubuntu0.2
In general, a standard system update will make all the necessary changes.
