f5ef6999daddcffb2197ac8414aebba8The 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.

0f6ac7dc63f09be9bc5d5e81c51bf6c0This Metasploit module exploits a logic error in OpenSSL by impersonating the server and sending a specially-crafted chain of certificates, resulting in certain checks on untrusted certificates to be bypassed on the client, allowing it to use a valid leaf certificate as a CA certificate to sign a fake certificate. The SSL/TLS session is then proxied to the server allowing the session to continue normally and application data transmitted between the peers to be saved. The valid leaf certificate must not contain the keyUsage extension or it must have at least the keyCertSign bit set (see X509_check_issued function in crypto/x509v3/v3_purp.c); otherwise; X509_verify_cert fails with X509_V_ERR_UNABLE_TO_GET_ISSUER_CERT_LOCALLY. This Metasploit module requires an active man-in-the-middle attack.
244abcb9001d9746e6846f9785dab572Ubuntu Security Notice 2545-1 - A flaw was discovered in the automatic loading of modules in the crypto subsystem of the Linux kernel. A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. A flaw was discovered in the crypto subsystem when screening module names for automatic module loading if the name contained a valid crypto module name, eg. vfat(aes). A local user could exploit this flaw to load installed kernel modules, increasing the attack surface and potentially using this to gain administrative privileges. Various other issues were also addressed.
