(Red Hat Issues Fix) Dia Format String Bugs May Let Users Execute Arbitrary Code
SecurityTracker Alert ID:  1016205
SecurityTracker URL:  http://securitytracker.com/id/1016205
CVE Reference:   CVE-2006-2453, CVE-2006-2480   (Links to External Site)
Date:  Jun 2 2006
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): 0.95, possibly other versions
Description:   A vulnerability was reported in Dia. A remote user may be able to cause arbitrary code to be executed on the target user's system.

A remote user can create a file with a specially crafted filename. When the target user opens the file using Dia, a format string flaw will be triggered and arbitrary code may be executed [CVE-2006-2480]. KaDaL-X reported this vulnerability.

Other format string vulnerabilities also exist [CVE-2006-2453]. Hans de Goede discovered these vulnerabilities.

Impact:   A remote user can create a file that, when processed by the target user with Dia, will cause arbitrary code to be executed on the target user's system.
Solution:   Red Hat has released a fix.

- ---------------------------------------------------------------------

1. Summary:

Updated Dia packages that fix several buffer overflow bugs are now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

3. Problem description:

The Dia drawing program is designed to draw various types of diagrams.

Several format string flaws were found in the way dia displays certain
messages. If an attacker is able to trick a Dia user into opening a
carefully crafted file, it may be possible to execute arbitrary code as the
user running Dia. (CVE-2006-2453, CVE-2006-2480)

Users of Dia should update to these erratum packages, which contain
backported patches and are not vulnerable to these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
