Software has addressed the applicable CVEs.
Vulnerability Details
CVEID:
CVE-2016-8610
DESCRIPTION:
SSL/TLS protocol is vulnerable to a denial of service, caused by an error
when processing ALERT packets during a SSL handshake. By sending specially-
crafted packets, a remote attacker could exploit this vulnerability to cause
the application to stop responding.
CVSS Base Score: 7.5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/118296
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-2017-3730
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by a NULL pointer
dereference. By sending specially crafted parameters for a DHE or ECDHE key
exchange, a remote attacker could exploit this vulnerability to cause the
application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/121311
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:L)
CVEID:
CVE-2017-3731
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an out-of-bounds read
when using a specific cipher. By sending specially crafted truncated packets,
a remote attacker could exploit this vulnerability using CHACHA20/POLY1305 to
cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/121312
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:L)
CVEID:
CVE-2017-3732
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by a propagation error in the BN_mod_exp() function. An attacker could
exploit this vulnerability to obtain information about the private key.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/121313
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-2016-7055
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an error in a
Broadwell-specific Montgomery multiplication procedure. By sending specially
crafted data, a remote attacker could exploit this vulnerability to trigger
errors in public-key operations in configurations where multiple remote
clients select an affected EC algorithm and cause a denial of service.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/118748
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:L)
CVEID:
CVE-2017-3733
DESCRIPTION:
OpenSSL is vulnerable to a denial of service, caused by an error during a
renegotiate handshake when the original handshake did not include the
Encrypt-Then-Mac extension. A remote authenticated attacker could exploit
this vulnerability to cause the application to crash.
CVSS Base Score: 5.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/122091
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:L)
CVEID:
CVE-2016-6799
DESCRIPTION:
Apache Cordova Android could allow local attacker to obtain sensitive
information, caused by a flaw in the Log class. An attacker could exploit
this vulnerability to obtain sensitive information.
CVSS Base Score: 4.0
