Ubuntu Security Notice (C) 2005-2015 Canonical, Inc. / NASL script (C) 2006-2015 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related 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 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.
Update the affected packages.
Risk factor :
High / CVSS Base Score : 7.5
CVSS Temporal Score : 6.5
Public Exploit Available : true
