Updated dbus packages fixes the following security issues: Alban Crequy and Simon McVittie discovered several vulnerabilities in the D-Bus message daemon: 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-2014-3635). 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-2014-3636). 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-2014-3637). 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-2014-3638). dbus-daemon did not properly reject malicious connections from local users, resulting in a denial-of-service vulnerability (CVE-2014-3639).
