GLSA-200611-13 : Avahi: 'netlink' message vulnerability

low Nessus Plugin ID 23707

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200611-13 (Avahi: 'netlink' message vulnerability)

Avahi does not check that the netlink messages come from the kernel instead of a user-space process.
Impact :

A local attacker could exploit this vulnerability by crafting malicious netlink messages and trick Avahi to react to fake network changes. This could lead users to connect to untrusted services without knowing.
Workaround :

There is no known workaround at this time.

Solution

All Avahi users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=net-dns/avahi-0.6.15'
