OpenSSH 6.8p1 - 7.x < 7.1p2 ssh_packet_read_poll2() Packet Handling DoS
Medium Nessus Plugin ID 90924
SynopsisThe SSH server running on the remote host is affected by a denial of service vulnerability.
DescriptionAccording to its banner, the version of OpenSSH running on the remote host is 6.x equal to or greater than 6.8p1 or 7.x prior to 7.1p2. It is, therefore, affected by a denial of service vulnerability due to an out-of-bounds read error that occurs when handling packets. A remote attacker can exploit this to crash the service or disclose memory contents.
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
SolutionUpgrade to OpenSSH version 7.1p2 or later.
