VULNERABILITY DETAILS

The following information was provided by OpenSSL. In the case of IBM Security Virtual Server Protection for VMware System the Local Management Interface, SSH and the security management network ports are affected by the vulnerabilities with the exception of CVE-2011-1473 and CVE-2012-2131 which only affect the Local Management Interface. Further, for each vulnerability identified below, no authentication is required, the vulnerability is remotely exploitable, and no specialized knowledge is required.

CVE-ID: CVE-2011-1473

DESCRIPTION:


Multiple implementations of the Transport Layer Security (TLS) protocol, including SSL, are vulnerable to a denial of service. By initiating multiple SSL renegotiation handshakes or by initiating many SSL connections, a remote attacker could exploit this vulnerability to utilize CPU resources.

CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/71068 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-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 sent by an SSL peer.


CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/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 http://xforce.iss.net/xforce/xfdb/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 http://xforce.iss.net/xforce/xfdb/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.

CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/74100 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
