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.
