IBM Integrated Management Module II (IMM2) for System x, Flex and BladeCenter systems have addressed the following vulnerabilities in OpenSSL.
Summary
IBM Integrated Management Module II (IMM2) for System x, Flex
and BladeCenter systems have addressed the following
vulnerabilities in OpenSSL.
Vulnerability Details:
CVE-ID: 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 http://exchange.xforce.ibmcloud.com/vulnerabilities/113890
for 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)
CVE-ID: 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 http://exchange.xforce.ibmcloud.com/vulnerabilities/113889
for 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)
CVE-ID: CVE-2016-2179
Description: OpenSSL is vulnerable to a denial
of service. By sending specially crafted DTLS record fragments to
fill up buffer queues, a remote attacker could exploit this
vulnerability to open a large number of simultaneous connections
and consume all available memory resources.
CVSS Base Score: 5.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/116343
for 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:L)
CVE-ID: CVE-2016-2181
Description: OpenSSL is vulnerable to a denial
of service, caused by an error in the DTLS replay protection
implementation. By sending a specially crafted sequence number, a
remote attacker could exploit this vulnerability to cause valid
packets to be dropped.
CVSS Base Score: 5.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/116344
for 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:L)
CVE-ID: CVE-2016-6302
Description: OpenSSL is vulnerable to a denial
of service, caused by the failure to consider the HMAC size during
validation of the ticket length by the tls_decrypt_ticket function
A remote attacker could exploit this vulnerability using a ticket
that is too short to cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/vulnerabilities/117024
for 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:L)
CVE-ID: CVE-2016-6306
Description: OpenSSL is vulnerable to a denial
of service, caused by missing message length checks when parsing
certificates. A remote authenticated attacker could exploit this
vulnerability to trigger an out-of-bounds read and cause a denial
of service.
CVSS Base Score: 4.3
