-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - ------------------------------------------------------------------------- Debian Security Advisory DSA-3026-1 security@debian.org http://www.debian.org/security/ Florian Weimer September 16, 2014 http://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : dbus CVE ID : CVE-2014-3635 CVE-2014-3636 CVE-2014-3637 CVE-2014-3638 CVE-2014-3639 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.
