Synopsis
========
Improper hypertext validation might allow remote attackers to execute
arbitrary code.

Background
==========
VTE based, highly customizable terminal emulator

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 x11-terms/evilvte < 0.5.1 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate
to another package if one is available or wait for the
existing packages to be marked stable by their
architecture maintainers.

Description
===========
Steve Kemp of Debian identified a flaw in evilvte which does not
properly validate hypertext links. Please review the Debian bug report
referenced below.

Impact
======
Remote attackers could execute arbitrary code by enticing a user to
click a hyperlink in their terminal.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
Gentoo Security recommends that users unmerge evilvte:

# emerge --unmerge "x11-terms/evilvte"

References
==========
