Detail

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 the dbus-daemon crash, 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.

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

For the unstable distribution (sid), these problems have been fixed in version 1.8.8-1.

We recommend that you upgrade your dbus packages.

Title: SUSE-SU-2014:1146-1 -- Security update for dbus-1
Description: Various denial of service issues were fixed in the DBUS service. * CVE-2014-3638: dbus-daemon tracks whether method call messages expect a reply, so that unsolicited replies can be dropped. As currently implemented, if there are n parallel method calls in progress, each method reply takes O(n) CPU time. A malicious user could exploit this by opening the maximum allowed number of parallel connections and sending the maximum number of parallel method calls on each one, causing subsequent method calls to be unreasonably slow, a denial of service. * CVE-2014-3639: dbus-daemon allows a small number of "incomplete" connections (64 by default) whose identity has not yet been confirmed. When this limit has been reached, subsequent connections are dropped. Alban's testing indicates that one malicious process that makes repeated connection attempts, but never completes the authentication handshake and instead waits for dbus-daemon to time out and disconnect it, can cause the majority of legitimate connection attempts to fail.
