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.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-sci/gimps <= 23.9 >= 23.9-r1
2 app-sci/setiathome <= 3.08-r3 >= 3.08-r4

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=app-sci/setiathome-3.08-r4"
