msm1267 writes: Socat is the latest open source tool to come under suspicion that it is backdoored. A security advisory published Monday warned that the OpenSSL address implementation in Socat contains a hard-coded Diffie-Hellman 1024-bit prime number that was not prime. "The effective cryptographic strength of a key exchange using these parameters was weaker than the one one could get by using a prime p," the advisory said. "Moreover, since there is no indication of how these parameters were chosen, the existence of a trapdoor that makes possible for an eavesdropper to recover the shared secret from a key exchange that uses them cannot be ruled out." Socat said it has generated a new prime that is 2048 bits long; versions 220.127.116.11 and 2.0.0-b8 are affected. The advisory adds that a temporary workaround would be to disable the Diffie-Hellman ciphers.
