The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Augeas versions up to and including 1.8.0 are vulnerable to heap-based buffer overflow due to improper     handling of escaped strings. Attacker could send crafted strings that would cause the application using     augeas to copy past the end of a buffer, leading to a crash or possible code execution. (CVE-2017-7555)

Note that Nessus relies on the presence of the package as reported by the vendor.

Han Han of Red Hat discovered that augeas, a configuration editing tool, improperly handled some escaped strings. A remote attacker could leverage this flaw by sending maliciously crafted strings, thus causing an augeas-enabled application to crash or potentially execute arbitrary code.

An update for augeas is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Augeas is a configuration editing tool. It parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native config files.

Security Fix(es) :

* A vulnerability was discovered in augeas affecting the handling of escaped strings. An attacker could send crafted strings that would cause the application using augeas to copy past the end of a buffer, leading to a crash or possible code execution. (CVE-2017-7555)

This issue was discovered by Han Han (Red Hat).
