Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Mako is a template library written in Python. Prior to 1.3.12, on Windows, a URI using backslash traversal
 (e.g. \..\..\ secret.txt) bypasses the directory traversal check in Template.__init__ and the posixpath-
