| Description: | Description:
The remote host is missing an update to php4-universe
announced via advisory USN-147-1.
A security issue affects the following Ubuntu releases:
Ubuntu 4.10 (Warty Warthog)
Ubuntu 5.04 (Hoary Hedgehog)
The following packages are affected: libapache2-mod-php4 php4-pear
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
attacker could exploit this to execute arbitrary code with the web server's
privileges.
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:
- drupal - wordpress - phpwiki - horde3 - ewiki - egroupware - phpgroupware
These packages might be fixed by the community later.
The following common third party applications are affected as well, but
not packaged for Ubuntu:
- Serendipity - Postnuke - tikiwiki - phpwebsite
If you run any affected software, please upgrade them as soon as possible to
protect your server.
Solution:
The problem can be corrected by upgrading the affected package to
version 4:4.3.8-3ubuntu7.9 (for Ubuntu 4.10), or 4:4.3.10-10ubuntu3.1
(for Ubuntu 5.04). In general, a standard system upgrade is
sufficient to effect the necessary changes.
