Summary

IBM QRadar Network Security has addressed vulnerabilities in openssh.

Vulnerability Details

CVEID: CVE-2016-6515**
DESCRIPTION:** OpenSSH is vulnerable to a denial of service, caused by the failure to limit password lengths for password authentication by the auth_password function. A remote attacker could exploit this vulnerability using an overly long string to consume all available CPU resources.
CVSS Base Score: 7.5

CVEID: CVE-2016-6210**
DESCRIPTION:** OpenSSH could allow a remote attacker to obtain sensitive information, caused by the increased amount of time to calculate SHA256/SHA512 hash than BLOWFISH hash. An attacker could exploit this vulnerability using a covert timing channel to enumerate users on system that runs SSHD.
CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/115128&gt; for the current score
