How to fix?

Upgrade Alpine:3.10 python2 to version 2.7.15-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python2 package and not the python2 package as distributed by Alpine. See How to fix? for Alpine:3.10 relevant fixed versions and status.

python before versions 2.7.15, 3.4.9, 3.5.6rc1, 3.6.5rc1 and 3.7.0 is vulnerable to catastrophic backtracking in the difflib.IS_LINE_JUNK method. An attacker could use this flaw to cause denial of service.
