Synopsis
========
Format string vulnerabilities in Doomsday may lead to the execution of
arbitrary code.
Background
==========
Doomsday is a modern gaming engine for popular ID games like Doom,
Heretic and Hexen.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 games-fps/doomsday <= 1.8.6-r1 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
===========
Luigi Auriemma discovered that Doomsday incorrectly implements
formatted printing.
Impact
======
A remote attacker could exploit these vulnerabilities to execute
arbitrary code with the rights of the user running the Doomsday server
or client by sending specially crafted strings.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
Doomsday has been masked in Portage pending the resolution of these
issues. All Doomsday users are advised to uninstall the package until
further notice.
