OpenSSH < 6.6 Multiple Vulnerabilities
high Nessus Plugin ID 73079
Language:
Synopsis
The SSH server on the remote host is affected by multiple vulnerabilities.Description
According to its banner, the version of OpenSSH running on the remote host is prior to 6.6. It is, therefore, affected by the following vulnerabilities :- A flaw exists due to a failure to initialize certain data structures when makefile.inc is modified to enable the J-PAKE protocol. An unauthenticated, remote attacker can exploit this to corrupt memory, resulting in a denial of service condition and potentially the execution of arbitrary code. (CVE-2014-1692)
- An error exists related to the 'AcceptEnv' configuration setting in sshd_config due to improper processing of wildcard characters. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to bypass intended environment restrictions.
(CVE-2014-2532)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Upgrade to OpenSSH version 6.6 or later.See Also
