Security Bulletin: Vulnerabilities in OpenSSL affect IBM Flex System EN6131 40Gb Ethernet / IB6131 40Gb Infiniband Switch Firmware

Summary

OpenSSL vulnerabilities were disclosed on September 22 and 26, 2016 by the OpenSSL Project. OpenSSL is used by IBM Flex System EN6131 40Gb Ethernet / IB6131 40Gb Infiniband Switch Firmware. IBM Flex System EN6131 40Gb Ethernet / IB6131 40Gb Infiniband Switch Firmware has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2016-2180 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read in the TS_OBJ_print_bio function. A remote attacker could exploit this vulnerability using a specially crafted time-stamp file to cause the application to crash.
CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/115829&gt; 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-2016-2177 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 <https://exchange.xforce.ibmcloud.com/vulnerabilities/113890&gt; for the 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)

CVEID: 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 <https://exchange.xforce.ibmcloud.com/vulnerabilities/113889&gt; for the 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)
