10Strike LANState version 9.32 on x86 Host Check hostname SEH buffer overflow exploit.

The Megamos Crypto transponder is used in one of the most widely deployed electronic vehicle immobilizers. It is used among others in most Audi, Fiat, Honda, Volkswagen and Volvo cars. Such an immobilizer is an anti-theft device which prevents the engine of the vehicle from starting when the corresponding transponder is not present. This transponder is a passive RFID tag which is embedded in the key of the vehicle. In this paper, the authors have reverse-engineered all proprietary security mechanisms of the transponder, including the cipher and the authentication protocol which we publish here in full detail. This article reveals several weaknesses in the design of the cipher, the authentication protocol and also in their implementation.

FreeBSD Security Advisory - Crypto-NAK packets can be used to cause ntpd(8) to accept time from an unauthenticated ephemeral symmetric peer by bypassing the authentication required to mobilize peer associations. FreeBSD 9.3 and 10.1 are not affected. Various other issues have also been addressed.

Debian Linux Security Advisory 3417-1 - Tibor Jager, Jorg Schwenk, and Juraj Somorovsky, from Horst Gortz Institute for IT Security, published a paper in ESORICS 2015 where they describe an invalid curve attack in Bouncy Castle Crypto, a Java library for cryptography. An attacker is able to recover private Elliptic Curve keys from different applications, for example, TLS servers.
