Gentoo Linux Security Advisory GLSA 200712-05

                                        http://security.gentoo.org/

Severity: Normal
Title: PEAR::MDB2: Information disclosure
Date: December 09, 2007
Bugs: #198446
ID: 200712-05

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 &quot;&gt;=dev-php/PEAR-MDB2-2.5.0_alpha1&quot;
