| Description: | Summary:
The remote host is missing an update for the 'openssl' package(s) announced via the ALAS-2016-695 advisory.
Vulnerability Insight:
A vulnerability was discovered that allows a man-in-the-middle attacker to use a padding oracle attack to decrypt traffic on a connection using an AES CBC cipher with a server supporting AES-NI. (CVE-2016-2107, Important)
It was discovered that the ASN.1 parser can misinterpret a large universal tag as a negative value. If an application deserializes and later reserializes untrusted ASN.1 structures containing an ANY field, an attacker may be able to trigger an out-of-bounds write, which can cause potentially exploitable memory corruption. (CVE-2016-2108, Important)
An overflow bug was discovered in the EVP_EncodeUpdate() function. An attacker could supply very large amounts of input data to overflow a length check, resulting in heap corruption. (CVE-2016-2105, Low)
An overflow bug was discovered in the EVP_EncryptUpdate() function. An attacker could supply very large amounts of input data to overflow a length check, resulting in heap corruption. (CVE-2016-2106, Low)
An issue was discovered in the BIO functions, such as d2i_CMS_bio(), where a short invalid encoding in ASN.1 data can cause allocation of large amounts of memory, potentially resulting in a denial of service. (CVE-2016-2109, Low)
Affected Software/OS:
'openssl' package(s) on Amazon Linux.
Solution:
Please install the updated package(s).
CVSS Score:
