Trustix Secure Linux Security Advisory #2003-0007

Package name: kernel
Summary: Local root compromise
Date: 2003-03-18
Affected versions: TSL 1.01, 1.1, 1.2, 1.5

- --------------------------------------------------------------------------
Package description:
The kernel package contains the Linux kernel (vmlinuz), the core of your
Trustix Secure Linux operating system. The kernel handles the basic
functions of the operating system: memory allocation, process allocation,
device input and output, etc.

Problem description:
From the announce of 2.2.25 posted on linux-kernel:
The Linux 2.2 and Linux 2.4 kernels have a flaw in ptrace. This hole
allows local users to obtain full privileges. Remote exploitation of
this hole is not possible.

We recommend that all systems with this package installed be upgraded.
Note that swup with the default config will not update kernel packages
so you will need to update this package manually.
