OpenSSL is used by IBM Tealeaf Customer Experience. IBM Tealeaf Customer Experience has addressed the applicable CVEs. Vulnerability Details CVEID: CVE-2016-6304 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by multiple memory leaks in t1_lib.c during session renegotiation. By sending an overly large OCSP Status Request extension, a remote attacker could exploit this vulnerability to consume all available memory resources. CVSS Base Score: 7.5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117110 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) CVEID: CVE-2016-6305 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error in SSL_peek(). By sending specially crafted data, a remote authenticated attacker could exploit this vulnerability to cause the service to hang. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117111 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) CVEID: CVE-2016-2177 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the incorrect use of pointer arithmetic for heap-buffer boundary checks. By leveraging unexpected malloc behavior, a remote attacker could exploit this vulnerability to trigger an integer overflow and cause the application to crash. CVSS Base Score: 5.9 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113890 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H) CVEID: CVE-2016-2178 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DSA implementation that allows the following of a non-constant time codepath for certain operations. An attacker could exploit this vulnerability using a cache-timing attack to recover the private DSA key. CVSS Base Score: 5.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113889 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N) CVEID: CVE-2016-6307 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory allocation error in the logic prior to the excessive message length check. By initiating multiple connection attempts, a remote authenticated attacker could send an overly large message to exhaust all available memory resources. CVSS Base Score: 4.3 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/117113 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L) Affected Products and Versions IBM Tealeaf Customer Experience 8.7-9.0.2 Remediation/Fixes Product VRMF Remediation/First Fix IBM Tealeaf Customer Experience 9.0.2A PCA: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.2A_IBMTealeaf_PCA-3732-13_SecurityRollup_FixPack&includeSupersedes=0&source=fc Tealeaf CX: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.2.5269_9.0.2A_IBMTealeaf_CXUpgrade_FixPack5&includeRequisites=1&includeSupersedes=0&downloadMethod=http&source=fc IBM Tealeaf Customer Experience 9.0.2 PCA: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.2_IBMTealeaf_PCA-3682-13_SecurityRollup_FixPack&includeSupersedes=0&source=fc Tealeaf CX: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.2.1283_IBMTealeaf_CXUpgrade_FixPack5&includeRequisites=1&includeSupersedes=0&downloadMethod=http&source=fc IBM Tealeaf Customer Experience 9.0.1A PCA: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.1A_IBMTealeaf_PCA-3724-13_SecurityRollup_FixPack&includeSupersedes=0&source=fc Tealeaf CX: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.1.5118_9.0.1A_IBMTealeaf_CXUpgrade_FixPack6&includeRequisites=1&includeSupersedes=0&downloadMethod=http&source=fc IBM Tealeaf Customer Experience 9.0.1 PCA: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.1_IBMTealeaf_PCA-3673-13_SecurityRollup_FixPack&includeSupersedes=0&source=fc Tealeaf CX: http://www.ibm.com/support/fixcentral/swg/quickorder?parent=Enterprise%20Marketing%20Management&product=ibm/Other+software/Tealeaf+Customer+Experience&release=All&platform=All&function=fixId&fixids=9.0.1.1128_9.0.1_IBMTealeaf_CXUpgrade_FixPack6&includeRequisites=1&includeSupersedes=0&downloadMethod=http&source=fc IBM Tealeaf Customer Experience 9.0.0, 9.0.0A You can contact the Technical Support team for guidance.
