MiracleLinux 4 : openssh-5.3p1-123.AXS4 (AXSA:2017-2173:02)

medium Nessus Plugin ID 289209

Synopsis

The remote MiracleLinux host is missing a security update.

Description

The remote MiracleLinux 4 host has packages installed that are affected by a vulnerability as referenced in the AXSA:2017-2173:02 advisory.

 * A covert timing channel flaw was found in the way OpenSSH handled authentication of non-existent users. A remote unauthenticated attacker could possibly use this flaw to determine valid user names by measuring the timing of server responses. (CVE-2016-6210) CVE-2016-6210 sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
