Título:	Linux: MAC algorithms
Resumen:	This variable limits the types of MAC algorithms that SSH can use during; communication. MD5 and 96-bit MAC algorithms are considered weak and have been shown to increase; exploitability in SSH downgrade attacks. Weak algorithms continue to have a great deal of; attention as a weak spot that can be exploited with expanded computing power. An attacker that; breaks the algorithm could take advantage of a MiTM position to decrypt the SSH tunnel and capture; credentials and information.;; Note: This check fails if any MAC algorithms are found that are not specified in the VT preferences.
