CVE-2017-12133 [MEDIUM] GNU C Library vulnerabilities
Title: GNU C Library vulnerabilities
Summary: Several security issues were fixed in GNU C Library.
Florian Weimer discovered that the GNU C Library incorrectly handled
certain memory operations. A remote attacker could use this issue to cause
the GNU C Library to crash, resulting in a denial of service, or possibly
execute arbitrary code. This issue only affected Ubuntu 16.04 LTS.

## Abstract
Security metrics are not standardized, but international proposals such as the Common Vulnerability Scoring System (CVSS) for quantifying the severity of known vulnerabilities are widely used. Many CVSS aggregation mechanisms have been proposed in the literature. Nevertheless, factors related to the context of the System Under Test (SUT) are not taken into account in the aggregation process; vul
