Package        : kernel-patch-2.4.18-powerpc, kernel-image-2.4.18-1-alpha
Vulnerability  : mising boundary check
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2003-0985

Paul Starzetz discovered a flaw in bounds checking in mremap() in the
Linux kernel (present in version 2.4.x and 2.6.x) which may allow a
local attacker to gain root privileges.  Version 2.2 is not affected
by this bug.

For the stable distribution (woody) this problem has been fixed in
version 2.4.18-1woody3 for the powerpc architecture.

For the unstable distribution (sid) this problem will be fixed soon
with newly uploaded packages.

We recommend that you upgrade your kernel packages.  This problem has
been fixed in the upstream version 2.4.24 as well.


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.
