Synopsis:          Multiple local imwheel vulnerabilities
Advisory ID:       RHSA-2000:016-03

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

rpm --checksig --nogpg
