Rémi Denis-Courmont discovered that dbus, a message bus application, is not properly limiting the nesting level when examining messages with extensive nested variants. This allows an attacker to crash the dbus system daemon due to a call stack overflow via crafted messages.
For the stable distribution (lenny), this problem has been fixed in version 1.2.1-5+lenny2.
For the testing distribution (squeeze), this problem has been fixed in version 1.2.24-4.

We recommend that you upgrade your dbus packages.
