Detail
A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS Summary: Several security issues were fixed in DBus. Software Description: - dbus: simple interprocess messaging system Details: Simon McVittie discovered that DBus incorrectly handled the file descriptors message limit. A local attacker could use this issue to cause DBus to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3635) Alban Crequy discovered that DBus incorrectly handled a large number of file descriptor messages. A local attacker could use this issue to cause DBus to stop responding, resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3636) Alban Crequy discovered that DBus incorrectly handled certain file descriptor messages. A local attacker could use this issue to cause DBus to maintain persistent connections, possibly resulting in a denial of service. This issue only applied to Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. (CVE-2014-3637) Alban Crequy discovered that DBus incorrectly handled a large number of parallel connections and parallel message calls. A local attacker could use this issue to cause DBus to consume resources, possibly resulting in a denial of service. (CVE-2014-3638) Alban Crequy discovered that DBus incorrectly handled incomplete connections. A local attacker could use this issue to cause DBus to fail legitimate connection attempts, resulting in a denial of service. (CVE-2014-3639) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: Ubuntu 10.04 LTS: After a standard system update you need to reboot your computer to make all the necessary changes.

Title: | SUSE-SU-2014:1146-1 -- Security update for dbus-1 | ||
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. Security Issues: * CVE-2014-3638 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3638> * CVE-2014-3638 <http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2014-3638> | ||
