Security Bulletin


Summary

OpenSSL vulnerabilities were disclosed on March 1, 2016 by the OpenSSL Project. OpenSSL is used by ProtecTIER. ProtecTIER has addressed the applicable CVEs including the “DROWN: Decrypting RSA with Obsolete and Weakened eNcryption" vulnerability.

Vulnerability Details

CVEID: CVE-2016-0800
DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions. By using a server that supports SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle, an attacker could exploit this vulnerability to decrypt TLS sessions between clients and non-vulnerable servers. This vulnerability is also known as the DROWN attack.
CVSS Base Score: 7.4
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111139 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:N)



CVEID: CVE-2016-0797
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the BN_hex2bn/BN_dec2bn() function. An attacker could exploit this vulnerability using specially crafted data to cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111142 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:L)
