USN-1278-1: Linux (Maverick backport) vulnerabilities
First published: Thu Nov 24 2011(Updated: )

If KSM was being used, a local attacker could exploit this to crash the system, leading to a denial of service.

(CVE-2011-2491) Robert Swiecki discovered that mapping extensions were incorrectly handled. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2011-2496) It was discovered that the wireless stack incorrectly verified SSID lengths. A local attacker could exploit this to cause a denial of service or gain root privileges. (CVE-2011-2517)
