Debian DSA-3026-1 : dbus - security update

medium Nessus Plugin ID 77716

Language:

Synopsis

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

Description

Alban Crequy and Simon McVittie discovered several vulnerabilities in the D-Bus message daemon.

- CVE-2014-3635 On 64-bit platforms, file descriptor passing could be abused by local users to cause heap corruption in dbus-daemon, leading to a crash, or potentially to arbitrary code execution.

- CVE-2014-3636 A denial-of-service vulnerability in dbus-daemon allowed local attackers to prevent new connections to dbus-daemon, or disconnect existing clients, by exhausting descriptor limits.

- CVE-2014-3637 Malicious local users could create D-Bus connections to dbus-daemon which could not be terminated by killing the participating processes, resulting in a denial-of-service vulnerability.

- CVE-2014-3638 dbus-daemon suffered from a denial-of-service vulnerability in the code which tracks which messages expect a reply, allowing local attackers to reduce the performance of dbus-daemon.

- CVE-2014-3639 dbus-daemon did not properly reject malicious connections from local users, resulting in a denial-of-service vulnerability.

Solution

Upgrade the dbus packages.

For the stable distribution (wheezy), these problems have been fixed in version 1.6.8-1+deb7u4.
