Debian DSA-4285-1 : sympa - security update

critical Nessus Plugin ID 117297
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

Michael Kaczmarczik discovered a vulnerability in the web interface template editing function of Sympa, a mailing list manager. Owner and listmasters could use this flaw to create or modify arbitrary files in the server with privileges of sympa user or owner view list config files even if edit_list.conf prohibits it.

Solution

Upgrade the sympa packages.

For the stable distribution (stretch), this problem has been fixed in version 6.2.16~dfsg-3+deb9u1.
