Security Bulletin
Summary
SSLv3 contains a vulnerability that has been referred to as the Padding
Oracle On Downgraded Legacy Encryption (POODLE) attack. SSLv3 is enabled
in Informix Genero.
Vulnerability Details
CVEID: CVE-2014-3566
DESCRIPTION: Multiple products could allow a remote attacker to obtain
sensitive information, caused by a design error when using the SSLv3
protocol. A remote user with the ability to conduct a man-in-the-middle
attack could exploit this vulnerability via the POODLE (Padding Oracle On
Downgraded Legacy Encryption) attack to decrypt SSL sessions and calculate
the plaintext of secure connections.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/97013 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)
CVEID: CVE-2014-0076
DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive
information, caused by an implementation error in ECDSA (Elliptic Curve
Digital Signature Algorithm). An attacker could exploit this vulnerability
using the FLUSH+RELOAD cache side-channel attack to recover ECDSA nonces.
CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91990 for the
