Package        : kernel-patch-2.4.17-mips
Vulnerability  : integer overflow
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2003-0961

RedHat and SuSE kernel and security teams revealed an integer overflow
in the do_brk() function of the Linux kernel allows local users to
gain root privileges.

For the stable distribution (woody) this problem has been fixed in
version 2.4.17-0.020226.2.woody4.  Other architectures are already or
will be fixed separately.

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

We recommend that you upgrade your kernel image packages for the mips
and mipsel architectures.  This problem has been fixed in the upstream
version 2.4.23 as well and is also present in 2.4.24, of course.


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.
