The following vulnerabilities in OpenSSL affect IBM BladeCenter Switches. The IBM BladeCenter Switches listed below have addressed the vulnerabilities.
Vulnerability Details:
CVE-ID: CVE-2015-3194
Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when verifying certificates via a malformed routine. An attacker could exploit this vulnerability using signature verification routines with an absent PSS parameter to cause any certificate verification operation to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/108503> 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-2015-3195
Description: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a memory leak in a malformed X509_ATTRIBUTE structure. An attacker could exploit this vulnerability to obtain CMS data and other sensitive information.
CVSS Base Score: 5.3

Firmware fix versions are available on Fix Central:
<http://www.ibm.com/support/fixcentral/>.
You should verify applying this fix does not cause any compatibility issues. The fix disables MD5 signature hash by default. If you change the default setting after applying the fix you will expose yourself to the attack described above. IBM recommends that you review your entire environment to identify other areas where you have enabled the MD5 signature hash and take appropriate mitigation and remediation actions.
