I'm on Debian jessie the stable release. I noticed that version of
wpa_supplicant is vulnerable to DoS attacks according to CVE-2015-8041:
Multiple integer overflows in the NDEF record parser in hostapd before 2.5 and wpa_supplicant before 2.5 allow remote attackers to cause a denial of service (process crash or infinite loop) via a large payload length field value in an (1) WPS or (2) P2P NFC NDEF record, which triggers an out-of-bounds read.
On the stable release the available version is
wpa_supplicant 2.3, with a regular
sources.list it's not possible to upgrade the current version to
wpa_supplicant 2.5 , Why does Debian stable keep some obsolete (vulnerable) packages?
