NVD Description

Note: Versions mentioned in the description apply only to the upstream python36:3.6/python3-sqlalchemy package and not the python36:3.6/python3-sqlalchemy package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

In pygments 1.1+, fixed in 2.7.4, the lexers used to parse programming languages rely heavily on regular expressions. Some of the regular expressions have exponential or cubic worst-case complexity and are vulnerable to ReDoS. By crafting malicious input, an attacker can cause a denial of service.
