This update has been rated as having important security impact by the Red

Hat Security Response Team.

3. Description:

 

The libxml2 packages provide a library that allows you to manipulate XML

files. It includes support to read, modify, and write XML and HTML files.

 

A heap-based buffer overflow flaw was found in the way libxml2 handled long

XML entity names. If an application linked against libxml2 processed

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

or, possibly, execute arbitrary code. (CVE-2008-3529)

 

A denial of service flaw was found in the way libxml2 processed certain

content. If an application linked against libxml2 processed malformed XML

content, it could cause the application to use an excessive amount of CPU

time and memory, and stop responding. (CVE-2003-1564)

 

All users of libxml2 are advised to upgrade to these updated packages,

which contain backported patches to resolve these issues.
