Debian DSA-3233-1 : wpa - security update

medium Nessus Plugin ID 83061

Language:

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.
