Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

Security Fix(es) :

A heap-based buffer overflow flaw was found in the way libxml2 parsed certain crafted XML input. A remote attacker could provide a specially crafted XML file that, when opened in an application linked against libxml2, would cause the application to crash or execute arbitrary code with the permissions of the user running the application.
(CVE-2016-1834, CVE-2016-1840)

Multiple denial of service flaws were found in libxml2.
