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.
