IBM Waston Explorer, formerly known as IBM InfoSphere Data Explorer, is
affected by some of the vulnerabilities that The OpenSSL Project reported on
August 6, 2014.
Watson Explorer is affected by the following vulnerabilities from the OpenSSL
Security Advisory [6 Aug 2014]
DESCRIPTION: The issue affects OpenSSL clients and allows a malicious server
to crash the client with a null pointer dereference (read) by specifying an
SRP ciphersuite even though it was not properly negotiated with the client.
This can be exploited through a Denial of Service attack.
DESCRIPTION: If a multithreaded client connects to a malicious server using a
resumed session and the server sends an ec point format extension it could
write up to 255 bytes to freed memory.
DESCRIPTION: A flaw in the OpenSSL SSL/TLS server code causes the server to
negotiate TLS 1.0 instead of higher protocol versions when the ClientHello
message is badly fragmented. This allows a man-in-the-middle attacker to force
a downgrade to TLS 1.0 even if both the server and the client support a higher
protocol version, by modifying the client's TLS records.
DESCRIPTION: A malicious client or server can send invalid SRP parameters and
overrun an internal buffer. Only applications which are explicitly set up for
SRP use are affected.
Affected Products and Versions
