Inkscape is an Open Source vector graphics editor using the W3C standard Scalable Vector Graphics (SVG) file format.
Joxean Koret has discovered that Inkscape incorrectly allocates memory when opening an SVG file, creating the possibility of a buffer overflow if the SVG file being opened is specially crafted.
An attacker could entice a user into opening a maliciously crafted SVG file, allowing for the execution of arbitrary code on a machine with the privileges of the user running Inkscape.
There is no known workaround at this time.
All Inkscape users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-gfx/inkscape-0.43"
