Dia is a gtk+ based diagram creation program released under the GPL license.
Joxean Koret discovered that the SVG import plugin in Dia fails to properly sanitise data read from an SVG file.
An attacker could create a specially crafted SVG file, which, when imported into Dia, could lead to the execution of arbitrary code.
There is no known workaround at this time.
All Dia users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-office/dia-0.94-r3"
