IBM Security Network Intrusion Prevention System can be affected by vulnerabilities in OpenSSL (CVE-2011-4576, CVE-2011-4619, CVE-2012-2131 and CVE-2012-1165)

IBM Security Network Intrusion Prevention Systems can be affected by several vulnerabilities in OpenSSL. These vulnerabilities include obtaining sensitive information, denial of service and code execution vulnerabilities that could be exploited remotely by an attacker.

VULNERABILITY DETAILS

The following information was provided by OpenSSL. In the case of IBM Security Network Intrusion Prevention System the Local Management Interface, SSH and the security management network ports are affected by the vulnerabilities with the exception of CVE-2012-2131, which only affects the Local Management Interface. Furthermore, for each vulnerability that is identified below, no authentication is required, the vulnerability is remotely exploitable, and no specialized knowledge is required.

CVE-ID: CVE-2011-4576

DESCRIPTION:
The SSL 3.0 implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly initialize data structures for block cipher padding, which might allow remote attackers to obtain sensitive information by decrypting the padding data that is sent by an SSL peer.

CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/72130 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector (AV:N/AC:L/Au:N/C:P/I:N/A:N)


CVE-ID: CVE-2011-4619

DESCRIPTION:
The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors.
CVSS Base Score: 4.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/72132 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector (AV:N/AC:L/Au:N/C:N/I:N/A:P)


CVE ID: CVE-2012-2131

DESCRIPTION:
Multiple integer signedness errors in crypto/buffer/buffer.c in OpenSSL 0.9.8v allow remote attackers to conduct buffer overflow attacks, and cause a denial of service (memory corruption) or possibly have unspecified other impact, via crafted DER data, as demonstrated by an X.509 certificate or an RSA public key. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-2110.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/75099 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)


CVE ID: CVE-2012-1165

DESCRIPTION:
The mime_param_cmp function in crypto/asn1/asn_mime.c in OpenSSL before 0.9.8u and 1.x before 1.0.0h allows remote attackers to cause a denial of service (NULL pointer dereference and application crash) via a crafted S/MIME message, a different vulnerability than CVE-2006-7250.
