3. Description:

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.

4. 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.

5. Bugs fixed (https://bugzilla.redhat.com/):

1296102 - CVE-2016-0718 expat: Out-of-bounds heap read on crafted input causing crash
