"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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
