Updated mailman packages fix security vulnerability

Publication date: 05 Jul 2020
Type: security
Affected Mageia releases : 7
CVE: CVE-2020-12137 , CVE-2020-12108 , CVE-2020-15011

Description

Updated mailman package fixes security vulnerability:

Up to mailman 2.1.29 when sending a file without a file extension (or an
unknown file extension) then the file is stored in the list archive with
the file extension .obj. Most web servers will try to assign a mime type
based on the file extension and entries in /etc/mime.types, where .obj is
usually not specified. This means the web server will send it out without
a mime type. 
The browser will then try to guess the MIME type based on the file's
content (MIME-sniffing). If the content is HTML then it will execute any
javascript contained, leading to a potential cross-site scripting
vulnerability.

The mailman package has been updated to version 2.1.30, fixing this bug
and other issues.  See the release announcement for details.
