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 BladeCenter Advanced Management Module (AMM). IBM BladeCenter Advanced Management Module (AMM) has addressed the vulnerabilities.

Vulnerability Details:

CVE-ID: 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

CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

CVE-ID: CVE-2015-3216

Description: OpenSSL shipped with Red Hat Enterprise Linux is vulnerable to a denial of service, caused by an out-of-bounds memory read error in ssleay_rand_bytes() function. By sending specially crafted data, a remote attacker could exploit this vulnerability to cause the application to crash.

CVSS Base Score: 5
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/103915&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-8176

Description: OpenSSL could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an invalid free error when application data between the ChangeCipherSpecand 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 code on the system.

CVE-ID: 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 <http://exchange.xforce.ibmcloud.com/vulnerabilities/103779&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: 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 Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: 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 Base Score: 5

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

CVE-ID: 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.
