Debian DSA-2707-1 : dbus - denial of service

low Nessus Plugin ID 66905

Language:

Synopsis

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

Description

Alexandru Cornea discovered a vulnerability in libdbus caused by an implementation bug in _dbus_printf_string_upper_bound(). This vulnerability can be exploited by a local user to crash system services that use libdbus, causing denial of service. Depending on the dbus services running, it could lead to complete system crash.

The oldstable distribution (squeeze) is not affected by this problem.

Solution

Upgrade the dbus packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.6.8-1+deb7u1.
