Update Information:

This update addresses a security vulnerability identified as CVE-2015-1863 . More information on this vulnerability is provided by upstream at https://w1.fi/security/2015-1/wpa_supplicant-p2p-ssid-overflow.txt . An extract:

Attacker (or a system controlled by the attacker) needs to be within radio range of the vulnerable system to send a suitably constructed management frame that triggers a P2P peer device information to be created or updated.

The vulnerability is easiest to exploit while the device has started an active P2P operation (e.g., has ongoing P2P_FIND or P2P_LISTEN control interface command in progress). However, it may be possible, though significantly more difficult, to trigger this even without any active P2P operation in progress.

This update can be installed with the "yum" update program.  Use
su -c 'yum update wpa_supplicant' at the command line.
For more information, refer to "Managing Software with yum",
available at http://docs.fedoraproject.org/yum/.
