CVE-2015-8041: Integer Overflow
First published: Sun Aug 16 2015(Updated: )
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.
