Vulnerability Assessment Details
php4, php4-universe vulnerability
Detailed Explanation for this Vulnerability Assessment
These remote packages are missing security patches :
A remote code execution vulnerability has been discovered in the XMLRPC module
of the PEAR (PHP Extension and Application Repository) extension of PHP. By
sending specially crafted XMLRPC requests to an affected web server, a remote

In Ubuntu 5.04 (Hoary Hedgehog), the PEAR extension is unsupported (it is
contained in the php4-universe package which is part of universe). However,
since this is a highly critical vulnerability, that package was fixed as well.
Please note that many applications contain a copy of the affected XMLRPC code,
which must be fixed separately. The following packages may also be affected,
but are unsupported in Ubuntu:
These packages might be fixed by the community later.
The following common third party applications are affected as well, but not packaged
