mgv is a Postscript viewer with a Motif interface, based on Ghostview
|
|
and GNU gv.

|
|
<description>
|
|
<p>
|
|
mgv includes code from gv that does not properly boundary check
|
|
user-supplied data before copying it into process buffers.
|
|
</p>

|
<impact type="normal">
|
|
<p>
|
|
An attacker could entice a user to open a specially crafted Postscript
|
|
document with mgv and possibly execute arbitrary code with the rights
|
|
of the user running mgv.
|

<workaround>
|
|
<p>
|

There is no known workaround at this time.

mgv is currently unmaintained, and the mgv website no longer exists. As
|
|
such, the mgv package has been masked in Portage. We recommend that
|
|
users select an alternate Postscript viewer such as ghostview or
|
|
GSview, and unmerge mgv:
|
|
</p>
|
|
<code>
|
|
# emerge --unmerge "app-text/mgv"</code>
