Security Bulletin: Vulnerabilities in Open Source OpenSSL affect IBM Cisco SAN switches and directors (CVE-2016-2177 CVE-2000-1254 CVE-2016-2178).

Summary

Open Source OpenSSL is used by IBM Cisco SAN switches and directors. IBM Cisco SAN switches and directors has addressed the applicable CVEs.

Vulnerability Details

Relevant CVE Information:

CVEID: CVE-2000-1254**
DESCRIPTION:** OpenSSL could allow a remote attacker to obtain sensitive information, caused by the improper handling of C bitwise-shift operations that exceed the size of an expression by crypto/rsa/rsa_gen.c. An attacker could exploit this vulnerability to defeat cryptographic protection mechanisms and decrypt data.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113136 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

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 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)

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 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)
