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


pygments could be made to hang if it opened a specially crafted file.

Software Description:
- pygments: Generic syntax highlighter


It was discovered that Pygments incorrectly handled parsing SML files. If a
user or automated system were tricked into parsing a specially crafted SML
file, a remote attacker could cause Pygments to hang, resulting in a denial
of service.

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 20.10:
python3-pygments 2.3.1+dfsg-4ubuntu0.1

Ubuntu 20.04 LTS:
python-pygments 2.3.1+dfsg-1ubuntu2.1
