Flashes (Alerts)
Abstract
Certain network-based attacks can cause the administration interface server to reboot (CVE-2011-4619 and CVE-2011-3210). Control data may be leaked from pad regions of cipher blocks (CVE-2011-4576).
Also Release 11.2 adds the ability for the client to install their own X509v3 certificate (CVE-2012-4829).

VULNERABILITY DETAILS:
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:
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/72132 for the current score
CVSS Environmental Score*: Unknown
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P)
AFFECTED PRODUCTS: IBM XIV Storage System Gen3 (MTMN 2810 and 2812) running releases 11.0 through 11.1.1.
REMEDIATION: Upgrade to Release 11.2 or higher code.
VENDOR FIX(ES): For XIV Gen 3 systems running a release lower than 11.2 contact IBM to have your system upgraded to release 11.2 or higher.
WORKAROUND(S): None known, apply fixes.
MITIGATION(S): Limit network access to the XIV system’s management interfaces.
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:
CVSS Base Score: 5

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
AFFECTED PRODUCTS: IBM XIV Storage System Gen3 (MTMN 2810 and 2812) running releases 11.0 through 11.1.1.
REMEDIATION: Upgrade to Release 11.2 or higher code.
VENDOR FIX(ES): For XIV Gen 3 systems running a release lower than 11.2 contact IBM to have your system upgraded to release 11.2 or higher.
WORKAROUND(S): None known, apply fixes.
MITIGATION(S): Limit network access to the XIV system’s management interfaces.
CVE ID: CVE-2011-3210
DESCRIPTION: The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through 0.9.8r and 1.0.x before 1.0.0e does not ensure thread safety during processing of handshake messages from clients, which allows remote attackers to cause a denial of service (daemon crash) via out-of-order messages that violate the TLS protocol.
