Immunix OS Security Advisory
Packages updated: kernel-2.2.19
Affected products: Immunix OS 7.0 and 6.2
Bugs fixed: immunix/1760
Date: Fri Oct 19 2001
Advisory ID: IMNX-2001-70-035-01
Author: Seth Arnold <sarnold@wirex.com>
-----------------------------------------------------------------------
Description:
Rafal Wojtczuk has found two serious flaws in the Linux kernel, both
versions 2.2.19 and 2.4.11 are affected. The problems include deeply
nested symlinks spending arbitrary amounts of time in kernel code, and
yet another ptrace vulnerability. This release of kernel 2.2.19-8_imnx
comes with two patches to fix the problems, supplied in Rafal's
bugtraq post. We expect these patches to be included in 2.2.20 when it
is released, but in the meantime we are making updated 2.2.19 packages
available for our users.
Note that kernel installs are different than other .rpms -- usually,
one would want to use: rpm -ivh kernel-2.2.19-8_imnx.i386.rpm
then check the /boot directory, /etc/lilo.conf file, and re-run lilo
to install the new kernel. A reboot is required to complete the
installation.
