CVE-2018-14939 libreoffice: Use of realpath() in desktop/unx/source/start.c:get_app_path() allows for potential buffer overflow
The get_app_path function in desktop/unx/source/start.c in LibreOffice through 6.0.5 mishandles the realpath function in certain environments such as FreeBSD libc, which might allow attackers to cause a denial of service (buffer overflow and application crash) or possibly have unspecified other impact if LibreOffice is automatically launched during web browsing with pathnames controlled by a remote web site.

## 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

## Abstract
Modern software systems heavily use C/C++ based libraries.
Because of the weak memory model of C/C++, libraries may suffer from
vulnerabilities which can expose the applications to potential attacks. For example, a very
large number of return oriented programming gadgets exist in glibc that allow
stitching together semantically valid but malicious Turing-complete programs.
In spite of significant advances in attack detection and
