Synopsis
========
A vulnerability when handling database input in PEAR::MDB2 allows
remote attackers to obtain sensitive information.
Background
==========
PEAR::MDB2 is a database abstraction layer for PHP aimed to provide a
common API for all supported relational database management systems. A
LOB ("large object") is a database field holding binary data.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-php/PEAR-MDB2 < 2.5.0_alpha1 >= 2.5.0_alpha1
Description
===========
priyadi discovered that the request to store a URL string as a LOB is
treated as a request to retrieve and store the contents of the URL.
Impact
======
If an application using PEAR::MDB2 allows input of LOB values via a web
form, remote attackers could use the application as an indirect proxy
or obtain sensitive information, including "file://" URLs local to the
web server.
Workaround
==========
As a workaround, manually filter input before storing it as a LOB in
PEAR::MDB2.
Resolution
==========
All PEAR::MDB2 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-php/PEAR-MDB2-2.5.0_alpha1"
References
==========
