Synopsis

Format string vulnerabilities in Dia may lead to the execution of arbitrary code.

2. Impact Information

Background

Dia is a GTK+ based diagram creation program.

Description

KaDaL-X discovered a format string error within the handling of filenames. Hans de Goede also discovered several other format string errors in the processing of dia files.

Impact

By enticing a user to open a specially crafted file, a remote attacker could exploit these vulnerabilities to execute arbitrary code with the rights of the user running the application.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All Dia users should upgrade to the latest available version:

Code Listing 3.1
