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
