Security Bulletin: Vulnerabilities in OpenSSL affect IBM InfoSphere Information Server

Summary

OpenSSL vulnerabilities were disclosed by the OpenSSL Project. This includes the alternate chains certificate forgery vulnerability (CVE-2015-1793). OpenSSL is used by the Progress Software DataDirect Connect ODBC drivers which are shipped as a component of IBM InfoSphere Information Server. The Progress Software DataDirect Connect ODBC drivers have addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2015-1793 DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions, caused by an implementation error of the alternative certificate chain logic. An attacker could exploit this vulnerability to bypass the CA flag and other specific checks on untrusted certificates and issue an invalid certificate.

CVEID: CVE-2014-8176 DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by an invalid free error when application data between the ChangeCipherSpec and Finished messages is received by the DTLS peer. An attacker could exploit this vulnerability to trigger a segmentation fault or possibly corrupt memory and execute arbitrary

CVEID: CVE-2015-1790 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the improper handling of missing inner EncryptedContent by the PKCS#7 parsing code. An attacker could exploit this vulnerability using specially crafted ASN.1-encoded PKCS#7 blobs with missing content to trigger a NULL pointer dereference.
