(Linux Kernel: Multiple DoS and permission vulnerabilities)

Workaround

2.4 users may not be affected by CVE-2004-0497 if they do not use remote
network filesystems and do not have support for any such filesystems in
their kernel configuration. All 2.6 users are affected by the /proc
attribute issue and the only known workaround is to disable /proc support.

currently known for the issue. There is no known fix to CVE-2004-0447,
CVE-2004-0496 or CVE-2004-0565 other than to upgrade the kernel to a
patched version.
As a result, all users affected by any of these vulnerabilities should
upgrade their kernels to ensure the integrity of their systems.
