MGASA-2021-0245 - Updated python-pygments packages fix a security vulnerability

Publication date: 13 Jun 2021
Type: security
Affected Mageia releases: 7
CVE: CVE-2021-27291

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 (CVE-2021-27291).
