Date Reported:

24 Apr 2015

Affected Packages:

wpa

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 783148.
In Mitre's CVE dictionary: CVE-2015-1863.

More information:

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.

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.

For the unstable distribution (sid), this problem has been fixed in version 2.3-2.

We recommend that you upgrade your wpa packages.
