Fedora 20: wpa_supplicant Security Update
Summary
wpa_supplicant is a WPA Supplicant for Linux, BSD and Windows with support
for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE 802.1X/WPA
component that is used in the client stations. It implements key negotiation
with a WPA Authenticator and it controls the roaming and IEEE 802.11
authentication/association of the wlan driver.
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.
