USN-2352-1 (UBUNTU-CVE-2014-3635)
Vulnerability from osv_ubuntu – Published: 2014-09-22 17:08 – Updated: 2026-04-22 07:36 – Source websiteSimon 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)
