Red Hat: RHSA-2016-2824-01 Moderate: Expat XML Library Threat

red hat
Calendar Grey November 28, 2016
Scroller Redhat
Ubuntu security notification targets low susceptibility by updating the libxml2 XML toolkit, rectifying weaknesses and risks.
An update for expat is now available for Red Hat Enterprise Linux 6 and Red Hat Enterprise Linux 7

Solution

For details on how to apply this update, which includes the changes described in this advisory, refer to:

https://access.redhat.com/articles/11258

After installing the updated packages, applications using the Expat library must be restarted for the update to take effect.

Summary

Expat is a C library for parsing XML documents.
Security Fix(es):
* An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application. (CVE-2016-0718)
Red Hat would like to thank Gustavo Grieco for reporting this issue.
