Caldera Systems, Inc. Security Advisory

Subject: several security problems in linux kernel
Advisory number: CSSA-2001-012.0
Issue date: 2001 April, 3
Cross reference:
______________________________________________________________________________


1. Problem Description

During code audits of the Linux Kernel several security problems
have been found. Some of them allow a local attacker to gain
root privileges through race conditions, others allow reading
and possibly writing of random kernel memory.

With these patches now being available in the 2.2.19 kernel, this
update backports them to the kernels used in our products.

2. Vulnerable Versions

System Package
-----------------------------------------------------------
OpenLinux 2.3 All packages previous to
linux-2.2.10-12

OpenLinux eServer 2.3.1 All packages previous to
and OpenLinux eBuilder linux-2.2.14-11S

OpenLinux eDesktop 2.4 All packages previous to
linux-2.2.14-7

3. Solution

Workaround

none

The proper solution is to upgrade to the latest packages.

4. OpenLinux 2.3
