Mandriva Linux Security Advisory MDKSA-2006:101
http://www.mandriva.com/security/
_______________________________________________________________________

Package : squirrelmail
Date : June 14, 2006
Affected: Corporate 3.0
_______________________________________________________________________

Problem Description:

A PHP remote file inclusion vulnerability in functions/plugin.php
in SquirrelMail 1.4.6 and earlier, if register_globals is enabled and
magic_quotes_gpc is disabled, allows remote attackers to execute
arbitrary PHP code via a URL in the plugins array parameter.

NOTE: this issue has been disputed by third parties, who state that
Squirrelmail provides prominent warnings to the administrator when
register_globals is enabled.

Updated packages are patched to address these issues.
