CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-0204

DESCRIPTION: The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before
0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL 
servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate 
brute-force decryption by offering a weak ephemeral RSA key in a noncompliant
role, related to the "FREAK" issue. NOTE: the scope of this CVE is only client
code based on OpenSSL, not EXPORT_RSA issues associated with servers or other
TLS implementations.

CVSS Base Score: 4

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/99707

CVSS Vector: (AV:N/AC:M/Au:N/C:M/I:P/A:N)

CVEID: CVE-2015-2808

DESCRIPTION: The RC4 algorithm, as used in the TLS protocol and SSL protocol,
does not properly combine state data with key data during the initialization 
phase, which makes it easier for remote attackers to conduct 
plaintext-recovery attacks against the initial bytes of a stream by sniffing 
network traffic that occasionally relies on keys affected by the Invariance 
Weakness, and then using a brute-force approach involving LSB values, aka the
"Bar Mitzvah" issue.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/101851

CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

CVEID: CVE-2015-1916

DESCRIPTION: Server applications which use the IBM Java Secure Socket 
Extension provider to accept SSL/TLS connections are vulnerable to a denial of
service attack due to an unspecified vulnerability.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/101995
