Buffer overflows in Dia XFig import

Subject: Buffer overflows in Dia XFig import
Date: 29 Mar 2006 21:27:42 -0000
A security review kindly performed by infamous41md has turned up three buffer 
overflow vulnerabilities in the XFig import plug-in in Dia, a diagramming tool 
for Gtk that runs on both Winddows and Unix.  While the XFig format is not the 
native format of Dia, a specially crafted XFig file could cause arbitrary code 
execution *if* loaded into Dia.

The vulnerabilities affect versions 0.87 through 0.94 as well as prereleases 
1-5 of 0.95, after which it is fixed in the source and later prereleases.  A 
patch against the 0.94 release has been attached to the announcement on the 
dia-list at http://mail.gnome.org/archives/dia-list/2006-March/msg00149.html
