(Debian Issues Fix) libgda2 Format String Bugs May Let Users Execute Arbitrary Code
SecurityTracker Alert ID:  1015109
SecurityTracker URL:  http://securitytracker.com/id/1015109
CVE Reference:   CVE-2005-2958   (Links to External Site)
Date:  Oct 26 2005
Impact:   Execution of arbitrary code via local system, Execution of arbitrary code via network, User access via local system, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in libgda2. A user may be able to cause a target application to execute arbitrary code.

The gda2 library contains two format string flaws, one in the gda_log_error() function and the other in the gda_log_message() function. User-supplied input is processed without proper validation and without the proper format string specifiers.

A user may be able to supply specially crafted input to cause an application that uses the library to execute arbitrary code.

The flaw resides in 'gda-log.c'.

Steve Kemp reported this vulnerability.

Impact:   A user may be able to cause a target application to execute arbitrary code, potentially with elevated privileges (depending on the application that uses the affected library).
Solution:   Debian has issued a fix.

Package        : libgda2
Vulnerability  : format string
Problem type   : local
Debian-specific: no
CVE ID         : CAN-2005-2958

Steve Kemp discovered two format string vulnerabilities in libgda2,
the GNOME Data Access library for GNOME2, which may lead to the
execution of arbitrary code in programs that use this library.

The old stable distribution (woody) is not affected by these problems.

For the stable distribution (sarge) these problems have been fixed in
version 1.2.1-2sarge1.

For the unstable distribution (sid) these problems will be fixed soon.

We recommend that you upgrade your libgda2 packages.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
