Synopsis

Improper file ownership allows user-owned files to be run with root
privileges by init scripts.
Background
==========
GIMPS is a client for the distributed Great Internet Mersenne Prime
Search. SETI@home is the client for the Search for Extraterrestrial
Intelligence (SETI) project. ChessBrain is the client for the
distributed chess supercomputer.

Description
===========
GIMPS, SETI@home and ChessBrain ebuilds install user-owned binaries and
init scripts which are executed with root privileges.
Impact
======
This could lead to a local privilege escalation or root compromise.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All GIMPS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-sci/gimps-23.9-r1"
All SETI@home users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-sci/setiathome-3.08-r4"
All ChessBrain users should upgrade to the latest version:
