1. Topic:

gpm-root (part of the gpm packge) fails to drop gid 0
priviledges when executing user commands.

Red Hat Linux 6.0 – alpha i386 sparc

3. Problem description:

gpm is a cut and paste utility and mouse server for virtual
consoles. As part of this package, the gpm-root program allows
people to define menus and actions for display when clicking on the
background of current tty.

The current gpm-root program fails to correctly give up the
group id 0 membership for user defined menus. If you are running
gpm-root on your system then you are at risk.

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.
