Fedora: 2,1: kernel Privilege change vulnerability
Summary
The kernel package contains the Linux kernel (vmlinuz), the core of any
Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.
During an audit of the Linux kernel, SUSE discovered a flaw in the
Linux kernel that inappropriately allows an unprivileged user to
change the group ID of a file to his/her own group ID.
The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0497 to this issue.
All Fedora Core 2 users are advised to upgrade their kernels to the
packages associated with their machine architectures and configurations
as listed in this erratum.

CORE 1:
Fedora Update Notification
FEDORA-2004-206
2004-07-02
The kernel package contains the Linux kernel (vmlinuz), the core of your
Fedora Core Linux operating system. The kernel handles the basic functions
of the operating system: memory allocation, process allocation, device
input and output, etc.
During an audit of the Linux kernel, SUSE discovered a flaw that allowed
a user to make unauthorized changes to the group ID of files in certain
circumstances. In the 2.4 kernel, as shipped with Fedora Core 1,
the only way this could happen is through the kernel nfs server.
A user on a system that mounted a remote file system from a vulnerable
machine may be able to make unauthorized changes to the group ID of
exported files. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0497 to this issue.
Only Fedora Core 1 systems that are configured to share
file systems via NFS are affected by this issue.
Additionally, a number of issues were discovered with the
Broadcom 5820 driver. Until such time that these get fixed,
this driver has been disabled.
All Fedora Core 1 users are advised to upgrade their kernels
to the packages associated with their machine architectures
and configurations as listed in this erratum.

- add patch to fix missing checks in fchown() (CAN-2004-0497)
- Drop Broadcom 5820 driver due to code quality concerns.
