Debian The kernel module loader in Linux 2.2 and Linux 2.4 kernels has a flaw in ptrace.

Debian Security Advisory DSA 276-1                                        Martin Schulze
April 3rd, 2003                
- --------------------------------------------------------------------------

Packages       : kernel-patch-2.4.17-s390, kernel-image-2.4.17-s390
Vulnerability  : local privilege escalation
Problem-Type   : local
Debian-specific: no
CVE Id         : CAN-2003-0127

The kernel module loader in Linux 2.2 and Linux 2.4 kernels has a flaw
in ptrace.  This hole allows local users to obtain root privileges by
using ptrace to attach to a child process that is spawned by the
kernel.  Remote exploitation of this hole is not possible.

This advisory only covers kernel packages for the S/390 architecture.
Other architectures will be covered by separate advisories.

For the stable distribution (woody) this problem has been fixed in the
following versions:
  kernel-patch-2.4.17-s390: version 0.0.20020816-0.woody.1.1
  kernel-image-2.4.17-s390: version 2.4.17-2.woody.2.2

The old stable distribution (potato) is not affected by this problem
for this architecture since s390 was first released with Debian
GNU/Linux 3.0 (woody).

For the unstable distribution (sid) this problem will be fixed soon.

We recommend that you upgrade your kernel-images packages immediately.

Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

  These files will probably be moved into the stable distribution on
  its next revision.
