Debian DSA-2777-1 : systemd - several vulnerabilities

high Nessus Plugin ID 70402

Language:

Synopsis

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

Description

Multiple security issues in systemd have been discovered by Sebastian Krahmer and Florian Weimer: Insecure interaction with DBUS could lead to the bypass of Policykit restrictions and privilege escalation or denial of service through an integer overflow in journald and missing input sanitising in the processing of X keyboard extension (XKB) files.

Solution

Upgrade the systemd packages.

For the stable distribution (wheezy), these problems have been fixed in version 44-11+deb7u4.
