Ubuntu 14.04 LTS / 14.10 / 15.04 : wpa vulnerability (USN-2577-1)

Medium Nessus Plugin ID 83052


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


It was discovered that wpa_supplicant incorrectly handled SSID information when creating or updating P2P peer entries. A remote attacker could use this issue to cause wpa_supplicant to crash, resulting in a denial of service, expose memory contents, or possibly execute arbitrary code.

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.
