IBM Dynamic System Analysis (DSA) Preboot has addressed the following vulnerabilities in OpenSSL.
Summary
IBM Dynamic System Analysis (DSA) Preboot has addressed the
following vulnerabilities in OpenSSL.
Vulnerability Details
CVEID: CVE-2016-2177
Description: OpenSSL is vulnerable to a denial
of service, caused by the incorrect use of pointer arithmetic for
heap-buffer boundary checks. By leveraging unexpected malloc
behavior, a remote attacker could exploit this vulnerability to
trigger an integer overflow and cause the application to crash.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113890
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:H)
CVEID: CVE-2016-2178
Description: OpenSSL could allow a remote
attacker to obtain sensitive information, caused by an error in the
DSA implementation that allows the following of a non-constant time
codepath for certain operations. An attacker could exploit this
vulnerability using a cache-timing attack to recover the private
DSA key.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/113889
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID: CVE-2016-2180
Description: OpenSSL is vulnerable to a denial
of service, caused by an out-of-bounds read in the TS_OBJ_print_bio
function. A remote attacker could exploit this vulnerability using
a specially crafted time-stamp file to cause the application to
crash.
CVSS Base Score: 7.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/115829
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)
CVEID: CVE-2016-2183
Description: OpenSSL could allow a remote
attacker to obtain sensitive information, caused by an error in the
DES/3DES cipher, used as a part of the SSL/TLS protocol. By
capturing large amounts of encrypted traffic between the SSL/TLS
server and the client, a remote attacker able to conduct a
man-in-the-middle attack could exploit this vulnerability to
recover the plaintext data and obtain sensitive information. This
vulnerability is known as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116337
for the current score
CVSS Environmental Score*: Undefined
