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. A remote
attacker could provide a specially crafted XML file that, when
processed by an application using libxml2, could cause that
application to crash. (CVE-2016-1762, CVE-2016-1833, CVE-2016-1835,
CVE-2016-1836, CVE-2016-1837, CVE-2016-1838, CVE-2016-1839,
CVE-2016-3627, CVE-2016-3705, CVE-2016-4447, CVE-2016-4448,
