Vulnerability Assessment Details

OpenSSH < 3.7.1

Vulnerability Assessment Summary
Checks for the remote SSH version

Detailed Explanation for this Vulnerability Assessment

You are running a version of OpenSSH which is older than 3.7.1

Versions older than 3.7.1 are vulnerable to a flaw in the buffer management
functions which might permit a possible hacker to execute arbitrary commands on this
host.

An exploit for this issue is rumored to exist.


Note that several distribution patched this hole without changing
the version number of OpenSSH. Since Nessus solely relied on the
banner of the remote SSH server to perform this check, this might
be a false positive.

If you are running a RedHat host, make sure that the command :
rpm -q openssh-server

Returns :
openssh-server-3.1p1-13 (RedHat 7.x)
openssh-server-3.4p1-7 (RedHat 8.0)
openssh-server-3.5p1-11 (RedHat 9)

Solution : Upgrade to OpenSSH 3.7.1
