3. Description:

 

libxml2 is a library for parsing and manipulating XML files. It includes

support for reading, modifying, and writing XML and HTML files.

 

An integer overflow flaw causing a heap-based buffer overflow was found in

the libxml2 XML parser. If an application linked against libxml2 processed

untrusted, malformed XML content, it could cause the application to crash

or, possibly, execute arbitrary code. (CVE-2008-4226)

 

A denial of service flaw was discovered in the libxml2 XML parser. If an

application linked against libxml2 processed untrusted, malformed XML

content, it could cause the application to enter an infinite loop.

(CVE-2008-4225)

 

Red Hat would like to thank Drew Yao of the Apple Product Security team for

reporting these issues.

 

Users of libxml2 are advised to upgrade to these updated packages, which

contain backported patches to correct these issues.
