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 a system that runs SSHD.
CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/115128> 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:N/A:N)
