Summary

OpenSSL vulnerabilities were disclosed on June 11, 2015 by the OpenSSL 
Project. This includes Logjam Attack on TLS connections using the 
Diffie-Hellman (DH) key exchange protocol (CVE-2015-4000). OpenSSL is used by
IBM InfoSphere Guardium. IBM InfoSphere Guardium has addressed the applicable
CVEs

Vulnerability Details

CVEID: CVE-2015-4000

DESCRIPTION: The TLS protocol could allow a remote attacker to obtain 
sensitive information, caused by the failure to properly convey a DHE_EXPORT 
ciphersuite choice. An attacker could exploit this vulnerability using 
man-in-the-middle techniques to force a downgrade to 512-bit export-grade 
cipher. Successful exploitation could allow an attacker to recover the session
key as well as modify the contents of the traffic. This vulnerability is 
commonly referred to as "Logjam".

CVSS Base Score: 4.3

score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2014-8176

DESCRIPTION: OpenSSL could allow a remote attacker to execute arbitrary code 
on the system, caused by an invalid free error when application data between 
the ChangeCipherSpec and Finished messages is received by the DTLS peer. An 
attacker could exploit this vulnerability to trigger a segmentation fault or 
possibly corrupt memory and execute arbitrary

CVSS Base Score: 6.5

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

CVEID: CVE-2015-1789

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an 
out-of-bounds read in X509_cmp_time. An attacker could exploit this 
vulnerability using a specially crafted certificate or CRL to trigger a 
segmentation fault.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/103779 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2015-1790

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the 
improper handling of missing inner EncryptedContent by the PKCS#7 parsing 
code. An attacker could exploit this vulnerability using specially crafted 
ASN.1-encoded PKCS#7 blobs with missing content to trigger a NULL pointer 
dereference.

CVSS Base Score: 5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/103780 for the current 
score

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2015-1791

DESCRIPTION: A double-free memory error in OpenSSL in the 
ssl3_get_new_session_ticket() function has an unknown impact. By returning a 
specially crafted NewSessionTicket message, an attacker could cause the client
to reuse a previous ticket resulting in a race condition.

CVSS Environmental Score*: Undefined

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

CVEID: CVE-2015-1792

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an error
when verifying a signedData message. An attacker could exploit this 
vulnerability using an unknown hash function OID to cause the application to 
enter into an infinite loop.
