                        SuSE Security Announcement

        Package:  kernel < 2.2.16
        Date:     Tue Jun 27 13:31:38 MEST 2000

        Affected SuSE versions: 6.1-6.4
        Vulnerability Type:     local compromise of setuid applications
        SuSE default package:   yes

A security hole was discovered in the package mentioned above. Please update it as soon as possible or disable the service if you are using this software on your SuSE Linux installation(s).

Other Linux distributions or operating systems might be affected as well, please contact your vendor for information about this issue.

Please note that we provide this information on an "as-is" basis only. There is no warranty whatsoever and no liability for any direct, indirect or incidental damage arising from this information or the installation of the update package.


1. Problem Description

The implementation of the capability feature of the kernel 2.2.x < 2.2.16 is faulty.

2. Impact

This bug allows an local adversary to exploit certain setuid applications to increase his/her privileges.

3. Solution

We are sorry about the late release of the new kernel, but the plain 2.2.16 kernel causes trouble with our patches and it also has a new security hole. After we solved all these problems, we hope, we could provide you with a more stable and more secure kernel.

Please, update the package from our FTP server. (These RPMs could also be used by SuSE Releases < 6.4!)

The Alpha kernel will be released within the next days. The PPC kernel could be build from lx_suse.rpm


Please verify these md5 checksums of the updates before installing:
