Summary

SSL vulnerabilities were disclosed on March 1, 2016 by the OpenSSL
Project. IBM DataPower Gateways has addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2016-0705
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a
double-free error when parsing DSA private keys. An attacker could exploit
this vulnerability to corrupt memory and cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111140 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-0797
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL
pointer dereference in the BN_hex2bn/BN_dec2bn() function. An attacker
could exploit this vulnerability using specially crafted data to cause a
denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111142 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)

CVEID: CVE-2016-0799
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive
information, caused by a memory error in the BIO_*printf() functions. An
attacker could exploit this vulnerability using specially crafted data to
trigger an out-of-bounds read.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111143 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2016-2842
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by
the failure to verify that a certain memory allocation succeeds by the
doapr_outch function. A remote attacker could exploit this vulnerability
using a specially crafted string to cause an out-of-bounds write or consume
an overly large amount of resources.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111304 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
