NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2016-1423.NASL description An update for flash-plugin is now available for Red Hat Enterprise Linux 5 Supplementary and Red Hat Enterprise Linux 6 Supplementary. Red Hat Product Security has rated this update as having a security impact of Critical. 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. The flash-plugin package contains a Mozilla Firefox compatible Adobe Flash Player web browser plug-in. This update upgrades Flash Player to version 11.2.202.632. Security Fix(es) : * This update fixes multiple vulnerabilities in Adobe Flash Player. These vulnerabilities, detailed in the Adobe Security Bulletin listed in the References section, could allow an attacker to create a specially crafted SWF file that would cause flash-plugin to crash, execute arbitrary code, or disclose sensitive information when the victim loaded a page containing the malicious SWF content.
