New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3.6

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

A NULL pointer derefernce flaw was found in the way OpenSSL verified signatures using the RSA PSS algorithm. A remote attacked could possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a TLS/SSL server using OpenSSL if it enabled client authentication.
(CVE-2015-3194)

A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7 and CMS data. A remote attacker could use this flaw to cause an application that parses PKCS#7 or CMS data from untrusted sources to use an excessive amount of memory and possibly crash. (CVE-2015-3195)

A race condition flaw, leading to a double free, was found in the way OpenSSL handled pre-shared key (PSK) identify hints. A remote attacker could use this flaw to crash a multi-threaded SSL/TLS client using OpenSSL. (CVE-2015-3196)

Solution

Run 'yum update openssl' to update your system.
