Vulnerability Details
CVEID:
CVE-2016-2108
DESCRIPTION:
OpenSSL could allow a remote attacker to execute arbitrary code on the
system, caused by a buffer underflow when deserializing untrusted ASN.1
structures and later reserializing them. An attacker could exploit this
vulnerability to corrupt memory and trigger an out-of-bounds write and
execute arbitrary code on the system.
CVSS Base Score: 8.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/112853
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H)
CVEID:
CVE-2016-2107
DESCRIPTION:
OpenSSL could allow a remote attacker to obtain sensitive information, caused
by an error when the connection uses an AES CBC cipher and the server support
AES-NI. A remote user with the ability to conduct a man-in-the-middle attack
could exploit this vulnerability via the POODLE (Padding Oracle On Downgraded
Legacy Encryption) attack to decrypt traffic.
