Synopsis
========
Evince improperly handles user-supplied data possibly allowing for the
execution of arbitrary code.
Background
==========
Evince is a document viewer for multiple document formats, including
PostScript.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-text/evince < 0.6.1-r3 >= 0.6.1-r3
Description
===========
Evince includes code from GNU gv that does not properly boundary check
user-supplied data before copying it into process buffers.
Impact
======
An attacker could entice a user to open a specially crafted PostScript
document with Evince and possibly execute arbitrary code with the
rights of the user running Evince.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All Evince users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-text/evince-0.6.1-r3"
