We've been monitoring things and the amount of speculative info flying around is incredible. Some claim it's the CPNI-957037 issue, thus affecting <5.2, others are indicating it's the unsafe signal handler issue fixed in 4.4. Granted, Red Hat does ship with a patched 4.3, but we have corrected all issues that we know to have existed with 4.3. And the veracity of the supposed "logs" are sketchy at best....

...troduced many new features and made some invasive changes. Changes since OpenSSH 5.1 ========================= Security: * This release changes the default cipher order to prefer the AES CTR modes and the revised "arcfour256" mode to CBC mode ciphers that are susceptible to CPNI-957037 "Plaintext Recovery Attack Against SSH". * This release also adds countermeasures to mitigate CPNI-957037-style attacks against the SSH protocol's use of CBC-mode ciphers. Upon detection of an invalid packet length or Message Authentication Code, ssh/sshd will continue read...
