Subject: Buffer overflows in Dia XFig import

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
