SUSE Security Update: Security update for dbus-1 ______________________________________________________________________________ Announcement ID: SUSE-SU-2014:1146-1 Rating: important References: #896453 Cross-References: CVE-2014-3638 Affected Products: SUSE Linux Enterprise Software Development Kit 11 SP3 SUSE Linux Enterprise Server 11 SP3 for VMware SUSE Linux Enterprise Server 11 SP3 SUSE Linux Enterprise Desktop 11 SP3 ______________________________________________________________________________ An update that fixes one vulnerability is now available. Description: Various denial of service issues were fixed in the DBUS service. * CVE-2014-3638: dbus-daemon tracks whether method call messages expect a reply, so that unsolicited replies can be dropped. As currently implemented, if there are n parallel method calls in progress, each method reply takes O(n) CPU time. A malicious user could exploit this by opening the maximum allowed number of parallel connections and sending the maximum number of parallel method calls on each one, causing subsequent method calls to be unreasonably slow, a denial of service. * CVE-2014-3639: dbus-daemon allows a small number of "incomplete" connections (64 by default) whose identity has not yet been confirmed. When this limit has been reached, subsequent connections are dropped. Alban's testing indicates that one malicious process that makes repeated connection attempts, but never completes the authentication handshake and instead waits for dbus-daemon to time out and disconnect it, can cause the majority of legitimate connection attempts to fail.
