Exploited by Malware: True

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the kernel-images packages immediately.

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).
