[FLSA-2004:1284] Updated kernel resolves security vulnerabilities



-----------------------------------------------------------------------
               Fedora Legacy Update Advisory

Synopsis:          Updated kernel resolves security vulnerabilities
Advisory ID:       FLSA:1284
Issue date:        2004-03-02
Product:           Red Hat Linux
Keywords:          Security
Cross references:  https://bugzilla.fedora.us/show_bug.cgi?id=1284
CVE Names:         CAN-2004-0077, CAN-2004-0075, CAN-2004-0010, 
CAN-2004-0003
-----------------------------------------------------------------------


---------------------------------------------------------------------
1. Topic:

Updated kernel packages that fix security vulnerabilities which may 
allow local users to gain root privileges are now available. These 
packages also resolve other minor issues.

2. Relevent releases/architectures:

Red Hat Linux 7.2 - i386, i586, i686, athlon
Red Hat Linux 7.3 - i386, i586, i686, athlon
Red Hat Linux 8.0 - i386, i586, i686, athlon

3. Problem description:

The Linux kernel handles the basic functions of the operating system.

Paul Starzetz discovered a flaw in return value checking in mremap() in 
the Linux kernel versions 2.4.24 and previous that may allow a local 
attacker to gain root privileges. No exploit is currently available; 
however this issue is exploitable. The Common Vulnerabilities and 
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0077 
to this issue.

The Vicam USB driver in kernel versions prior to 2.4.25 does not use the 
copy_from_user function to access userspace, which crosses security 
boundaries. The Common Vulnerabilities and Exposures project 
(cve.mitre.org) has assigned the name CAN-2004-0075 to this issue.

Arjan van de Ven discovered a flaw in ncp_lookup() in ncpfs that could
allow local privilege escalation. ncpfs is only used to allow a system 
to mount volumes of NetWare servers or print to NetWare printers. The 
Common Vulnerabilities and Exposures project (cve.mitre.org) has 
assigned the name CAN-2004-0010 to this issue.

Alan Cox found issues in the R128 Direct Render Infrastructure that 
could allow local privilege escalation. The Common Vulnerabilities and 
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0003 
to this issue.

All users are advised to upgrade to these errata packages, which contain
backported security patches that correct these issues.

Fedora Legacy would like to thank Paul Starzetz from ISEC for reporting 
the issue CAN-2004-0077, and Dominic Hargreaves for providing 
backported rpms for all issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade.  Only those
RPMs which are currently installed will be updated.  Those RPMs which 
are not installed but included in the list will not be updated.  Note 
that you can also use wildcards (*.rpm) if your current directory 
*only* contains the desired RPMs.

Please note that this update is also available via yum and apt.  Many
people find this an easier way to apply updates.  To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the 
appropriate RPMs being upgraded on your system.  This assumes that you 
have yum or apt-get configured for obtaining Fedora Legacy content. 
Please visit http://www.fedoralegacy.org/download for directions on how 
to configure yum and apt-get.

These packages are GPG signed by Fedora Legacy for security.  Our key is
available from http://www.fedoralegacy.org/about/security.php

You can verify each package with the following command:

    rpm --checksig -v <filename>

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the sha1sum with the following command:

    sha1sum <filename>

10. Special Notes:

If you use lilo, you will have to edit your lilo.conf file and shorten 
the label of this kernel.  The label is too long for lilo, but not for 
grub.
