Scientific Linux Security Update : libxml2 on SL6.x i386/x86_64 (20151207)

high Nessus Plugin ID 87235

Synopsis

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

Description

Several denial of service flaws were found in libxml2, a library providing support for reading, modifying, and writing XML and HTML files. A remote attacker could provide a specially crafted XML or HTML file that, when processed by an application using libxml2, would cause that application to use an excessive amount of CPU, leak potentially sensitive information, or in certain cases crash the application.
