Debian DSA-3233-1 : wpa - security update

medium Nessus Plugin ID 83061
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Debian host is missing a security-related update.

Description

The Google security team and the smart hardware research group of Alibaba security team discovered a flaw in how wpa_supplicant used SSID information when creating or updating P2P peer entries. A remote attacker can use this flaw to cause wpa_supplicant to crash, expose memory contents, and potentially execute arbitrary code.

Solution

Upgrade the wpa packages.

For the stable distribution (wheezy), this problem has been fixed in version 1.0-3+deb7u2. Note that this issue does not affect the binary packages distributed in Debian as the CONFIG_P2P is not enabled for the build.

For the upcoming stable distribution (jessie), this problem has been fixed in version 2.3-1+deb8u1.
