Synopsis:          Multiple local imwheel vulnerabilities
Advisory ID:       RHSA-2000:016-03
Issue date:        2000-04-20
Updated on:        2000-07-03

1. Topic:

Multiple vulnerabilities exist in imwheel.

2. Relevant releases/architectures:

Red Hat Powertools 6.1 - i386 alpha sparc
Red Hat Powertools 6.2 - i386 alpha sparc

3. Problem description:

Multiple local vulnerabilities exist in imwheel.

* Read access violations where there is no checking of the file
  itself, it follows a symlink blindly.

* Perl wrapper might allow other users on the machine to kill
  the imwheel process.

4. Solution:

Because the core functionality of imwheel has been incorporated
into many existing applications, removing imwheel will not
incur a significant loss of functionality.

If the machine which has imwheel installed is not a single user
machine we recommend removing imwheel. To remove imwheel run
this command:

rpm -e imwheel

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


6. RPMs required:


7. Verification:

MD5 sum                           Package Name
- --------------------------------------------------------------------------

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  <filename>

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 <filename>
