NOTE2: This bulletin was updated on February 15, 2018 to add 7.1 AIX client fix for NetApp Services.
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-2017-3733
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
