Ubuntu 14.04 LTS : wpa_supplicant vulnerability (USN-2577-1)

critical Nessus Plugin ID 83052

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2577-1 advisory.

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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
