Debian Security Advisory DSA 2665-1 (strongswan - authentication bypass)

Kevin Wojtysiak discovered a vulnerability in strongSwan, an IPsec based VPN solution. When using the OpenSSL plugin for ECDSA based authentication, an empty, zeroed or otherwise invalid signature is handled as a legitimate one. An attacker could use a forged signature to authenticate like a...

Three Questions for Billy Brumley on the OpenSSL Timing Attack

Timing attacks have been a problem for designers of cryptosystems–as well as for people implementing those systems–for a long time. They’ve plagued just about every popular system, and although practical attacks have been demonstrated many times, the problem and what can be done to defend against...

OpenSSL leaks ECDSA private key through a remote timing attack

Overview The OpenSSL ladder implementation for scalar multiplication of points on elliptic curves over binary fields is susceptible to a timing attack vulnerability. This vulnerability can be used to steal the private key of a TLS server that authenticates with ECDSA signatures and binary curves...
