Security Bulletin: IBM Sterling Connect:Direct for UNIX is affected by a security vulnerability in OpenSSL (CVE-2011-4576)


## Abstract A security vulnerability has been discovered in the OpenSSL libraries included in IBM Sterling Connect:Direct for UNIX that results in a security vulnerability in IBM Sterling Connect:Direct for UNIX. ## Content **VULNERABILITY DETAILS:** ** ****CVE ID**: [_CVE-2011-4576_](<http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2011-4576>) **DESCRIPTION:** IBM Sterling Connect:Direct for UNIX uses OpenSSL libraries for cryptography and is vulnerable to a security vulnerability discovered in the OpenSSL libraries. The SSL 3.0 implementation in OpenSSL version used by Sterling Connect:Direct for UNIX 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 [_https://exchange.xforce.ibmcloud.com/vulnerabilities/72130_](<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) ** AFFECTED VERSIONS:** IBM Sterling Connect:Direct for UNIX 4.0.00, all versions IBM Sterling Connect:Direct for UNIX 4.1.0, all versions **REMEDIATION:** • 4.0.00, all versions - apply the workaround • 4.1.0, all versions - apply the workaround • Alternatively, upgrade to 4.2.0, which is not affected by the vulnerability **_Workaround(s) & Mitigation(s):_** • Configure the product to use TLS and not SSL. **REFERENCES:** • [_Complete CVSS Guide_](<http://www.first.org/cvss/v2/guide>) • [_On-line Calculator V2_](<http://nvd.nist.gov/cvss.cfm?calculator&adv&version=2>) **RELATED INFORMATION:** • [_IBM Secure Engineering Web Portal_](<https://www-304.ibm.com/jct03001c/security/secure-engineering/>) • [_IBM Product Security Incident Response Blog _](<https://www.ibm.com/blogs/PSIRT>) **CHANGE HISTORY** 2 June 2014: Original Copy Published _*The CVSS Environment Score is customer environment specific and will ultimately impact the Overall CVSS Score.
