    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.
