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

CVEID:
CVE-2016-0798
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a memory leak in SRP
servers. An attacker could exploit this vulnerability using a specially
crafted username value to cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111141
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-2016-0702
DESCRIPTION:
OpenSSL could allow a local attacker to obtain sensitive information, caused
by a side-channel attack against a system based on the Intel Sandy-Bridge
microarchitecture. An attacker could exploit this vulnerability to recover
RSA keys.
CVSS Base Score: 2.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111144
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
CVEID:
CVE-2016-0704
DESCRIPTION:
OpenSSL could allow a remote attacker to bypass security restrictions. The
s2_srvr.c code overwrites the wrong bytes in the master-key when applying
Bleichenbacher protection for export cipher suites. An attacker could exploit
this vulnerability using a Bleichenbacher oracle to decrypt sessions.
CVSS Base Score: 5.9
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/111146
for the current score
CVSS Environmental Score*: Undefined

System has addressed the applicable CVEs.
Vulnerability Details
CVEID:
CVE-2016-0701
DESCRIPTION:
OpenSSL could allow a remote attacker to conduct man-in-the-middle attacks,
caused by the use of weak Diffie-Hellman parameters based on unsafe primes
that are generated and stored in X9.42-style parameter files. By performing
multiple handshakes using the same private DH exponent, an attacker could
exploit this vulnerability to conduct man-in-the-middle attacks.

DESCRIPTION:
OpenSSL could allow a remote attacker to conduct man-in-the-middle attacks,
caused by an error related to the negotiation of disabled SSLv2 ciphers by
malicious SSL/TLS clients. An attacker could exploit this vulnerability to
conduct man-in-the-middle attacks.
