Predictable RNG in the vulnerable Debian OpenSSL package
the What and the How
Recently, the Debian project announced an OpenSSL package vulnerability which they had been distributing for the last two years. This bug makes the PRNG predictable, affecting the keys generated by openssl and every other system that uses libssl (eg. openssh, openvpn).
We will talk about this bug (the speaker was the discoverer of this bug), its discovery and publication, its consequences, and exploitation. As well, we will demonstrate some exploitation tools.
