1. Problem Summary

The gpm-root program, included in the gpm package, contains a programming error whereby a call to setgid() fails, and defaults to the group of the gpm-root binary. The group for the gpm-root binary in the affected installations is root.
2. Impact
A user with console access can use this vulnerability to execute arbitrary commands with elevated priviledges.
3. Solution
Update the packages from our ftp server by running the following command for each package:
rpm -Fvh ftp_path_to_filename
Where ftp_path_to_filename is the following:
ftp://ftp.turbolinux.com/pub/updates/6.0/security/gpm-1.19.2-5.i386.rpm
ftp://ftp.turbolinux.com/pub/updates/6.0/security/gpm-devel-1.19.2-5.i386.rpm
The source RPM can be downloaded here:
ftp://ftp.turbolinux.com/pub/updates/6.0/SRPMS/gpm-1.19.2-5.src.rpm
**Note: You must rebuild and install the RPM if you choose to download and install the SRPM. Simply installing the SRPM alone WILL NOT CLOSE THE SECURITY HOLE.
Please verify the MD5 checksum of the update before you install:

  MD5 sum                               Package Name

These packages are GPG signed by Turbolinux for security. Our key
is available here:

To examine only the md5sum, use the following command:
rpm --checksig --nogpg name_of_rpm
