                   Red Hat, Inc. Security Advisory

Synopsis:          glint symlink vulnerability

Advisory ID:       RHSA-2000:062-03

Issue date:        2000-09-19

Updated on:        2000-09-19

Product:           Red Hat Linux

Keywords:          glint symlink rpm

Cross references:  N/A


1. Topic:

glint blindly follows a symlink in /tmp, overwriting the target file, so it

can conceivably be used to destroy any file on the system.

2. Relevant releases/architectures:

Red Hat Linux 5.2 - i386, alpha, sparc

3. Problem description:

If a specific symlink exists in /tmp, glint will open it and write to

it when run by root -- so destruction of any file is possible.

Note that glint does not work with RPM 3.0 or higher.  If you have RPM 3.0

or higher installed, just uninstall the glint package to remove this


4. Solution:

For each RPM for your particular architecture, run:

rpm -Fvh [filename]

where filename is the name of the RPM.

5. Bug IDs fixed (http://bugzilla.redhat.com/bugzilla for more info):

17544 - HUGE race condition in Glint

6. RPMs required:

Red Hat Linux 5.2:









7. Verification:

MD5 sum                           Package Name


b31d4a967bba65a2acc17c16ca75582c  5.2/SRPMS/glint-2.6.3-1.src.rpm

c9e1679ed0f8c1d15878eb8943be4b75  5.2/alpha/glint-2.6.3-1.alpha.rpm

a74b4697402e5ce8f34959ebe2d5327d  5.2/i386/glint-2.6.3-1.i386.rpm

20d74bc2360f6622dc2062654dde84f9  5.2/sparc/glint-2.6.3-1.sparc.rpm

These packages are GPG signed by Red Hat, Inc. for security.  Our key

is available at:


You can verify each package with the following command:

    rpm --checksig  

If you only wish to verify that each package has not been corrupted or

tampered with, examine only the md5sum with the following command:

    rpm --checksig --nogpg
