Vulnerability Details

Summary

IBM Integrated Management Module II (IMM2) for System x, Flex and BladeCenter systems have addressed the following vulnerabilities in OpenSSL.

Vulnerability Details:

CVE-ID: CVE-2016-2177

Description: OpenSSL is vulnerable to a denial of service, caused by the incorrect use of pointer arithmetic for heap-buffer boundary checks. By leveraging unexpected malloc behavior, a remote attacker could exploit this vulnerability to trigger an integer overflow and cause the application to crash.

CVSS Base Score: 5.9
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/113890&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H)

CVE-ID: CVE-2016-2178

Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DSA implementation that allows the following of a non-constant time codepath for certain operations. An attacker could exploit this vulnerability using a cache-timing attack to recover the private DSA key.

CVSS Base Score: 5.3
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/113889&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVE-ID: CVE-2016-2179

Description: OpenSSL is vulnerable to a denial of service. By sending specially crafted DTLS record fragments to fill up buffer queues, a remote attacker could exploit this vulnerability to open a large number of simultaneous connections and consume all available memory resources.

CVSS Base Score: 5.3
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/116343&gt; for 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:L)

CVE-ID: CVE-2016-2181

Description: OpenSSL is vulnerable to a denial of service, caused by an error in the DTLS replay protection implementation. By sending a specially crafted sequence number, a remote attacker could exploit this vulnerability to cause valid packets to be dropped.

CVSS Base Score: 5.3
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/116344&gt; for 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:L)

CVE-ID: CVE-2016-6302

Description: OpenSSL is vulnerable to a denial of service, caused by the failure to consider the HMAC size during validation of the ticket length by the tls_decrypt_ticket function A remote attacker could exploit this vulnerability using a ticket that is too short to cause a denial of service.

CVSS Base Score: 5.3
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/117024&gt; for 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:L)

CVE-ID: CVE-2016-6306

Description: OpenSSL is vulnerable to a denial of service, caused by missing message length checks when parsing certificates. A remote authenticated attacker could exploit this vulnerability to trigger an out-of-bounds read and cause a denial of service.

CVSS Base Score: 4.3
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/117112&gt; for current score
CVSS Environmental Score*: Undefined
