|Gentoo Linux Security Advisory
Title: D-Bus: Denial of Service (GLSA 200901-04)
Date: January 11, 2009
An error condition can cause D-Bus to crash.
D-Bus is a daemon providing a framework for applications to communicate with one another.
Vulnerable: < 1.2.3-r1
Unaffected: >= 1.2.3-r1
Architectures: All supported architectures
schelte reported that the dbus_signature_validate() function can trigger a failed assertion when processing a message containing a malformed signature.
A local user could send a specially crafted message to the D-Bus daemon, leading to a Denial of Service.
There is no known workaround at this time.
All D-Bus users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.2.3-r1"
