Synopsis

The remote Red Hat host is missing one or more security updates for pcre.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:1025 advisory.

PCRE is a Perl-compatible regular expression library.

Security Fix(es):

* Multiple flaws were found in the way PCRE handled malformed regular expressions. An attacker able to make an application using PCRE process a specially crafted regular expression could use these flaws to cause the application to crash or, possibly, execute arbitrary code. (CVE-2015-8385, CVE-2016-3191, CVE-2015-2328, CVE-2015-3217, CVE-2015-5073, CVE-2015-8388, CVE-2015-8391, CVE-2015-8386)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL pcre package based on the guidance in RHSA-2016:1025.
