Debian DSA-4356-1 : netatalk - security update

critical Nessus Plugin ID 119817
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

Jacob Baines discovered a flaw in the handling of the DSI Opensession command in Netatalk, an implementation of the AppleTalk Protocol Suite, allowing an unauthenticated user to execute arbitrary code with root privileges.

Solution

Upgrade the netatalk packages.

For the stable distribution (stretch), this problem has been fixed in version 2.2.5-2+deb9u1.
