Summary

OpenSSL vulnerabilities affect IBM BladeCenter Advanced Management Module (AMM).

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&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-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
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/108504&gt; for current score
