Improper file ownership allows user-owned files to be run with root privileges by init scripts.

2.  Impact Information


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.


GIMPS, SETI@home and ChessBrain ebuilds install user-owned binaries and init scripts which are executed with root privileges.


This could lead to a local privilege escalation or root compromise.

3.  Resolution Information


There is no known workaround at this time.


All GIMPS users should upgrade to the latest version:

Code Listing 3.1: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=sci-misc/gimps-23.9-r1"

All SETI@home users should upgrade to the latest version:

Code Listing 3.2: Resolution

# emerge --sync
# emerge --ask --oneshot --verbose ">=sci-misc/setiathome-3.03-r2"

All ChessBrain users should upgrade to the latest version:
