Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS : wpa, wpasupplicant vulnerability (USN-2383-1)

Medium Nessus Plugin ID 78468


The remote Ubuntu host is missing a security-related patch.


Jouni Malinen discovered that the wpa_cli tool incorrectly sanitized strings when being used with action scripts. A remote attacker could possibly use this issue to execute arbitrary commands.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected wpasupplicant package.
