IBM Security Network Protection has addressed vulnerabilities in OpenSSH.
Vulnerability Details
CVEID: CVE-2016-10011
DESCRIPTION: OpenSSH could allow a local authenticated attacker to obtain
sensitive information, caused by a privilege separation flaw. An attacker
could exploit this vulnerability to obtain host private key material and other
sensitive information.
CVSS Base Score: 5.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/119830 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2016-10009
DESCRIPTION: OpenSSH could allow a remote authenticated attacker to execute
arbitrary code on the system, caused by the loading of a specially crafted
PKCS#11 module across a forwarded agent channel. An attacker could exploit
this vulnerability to write files or execute arbitrary code on the system.
CVSS Base Score: 6.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/119828 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L)
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
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/115911 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
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 for the current
score
