Description

The vulnerability allows a remote non-authenticated attacker to perform service disruption.

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.

Mitigation
Install update from vendor's website.
