Advisory ID: FLSA:152532

Issue date: 2005-06-04

Product: Red Hat Linux, Fedora Core

Keywords: Bugfix

CVE Names: CAN-2004-1058 CAN-2004-1333 CAN-2005-0384

CAN-2005-0400 CAN-2005-0449 CAN-2005-0504

1. Topic:



Updated kernel packages that fix several security issues are now

available.



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



2. Relevant releases/architectures:



Red Hat Linux 7.3 - i386

Red Hat Linux 9 - i386

Fedora Core 1 - i386



3. Problem description:



This update includes fixes for several security issues:



A race condition was discovered. Local users could use this flaw to read

the environment variables of another process that is still spawning via

/proc/.../cmdline. (CAN-2004-1058)



An integer overflow was discovered in the vc_resize function. A local

user could cause a denial of service (kernel crash) via a short new

screen value, which leads to a buffer overflow. (CAN-2004-1333)



A flaw was discovered in the Linux PPP driver. On systems allowing

remote users to connect to a server using ppp, a remote client could

cause a denial of service (system crash). (CAN-2005-0384)



A flaw was discovered in ext2 filesystem support. When a new directory

is created, the ext2 block written to disk is not initialized, leading

to an information leak. (CAN-2005-0400)



A flaw in fragment queuing was discovered affecting the netfilter

subsystem. On systems configured to filter or process network packets

(for example those configured to do firewalling), a remote attacker

could send a carefully crafted set of fragmented packets to a machine

and cause a denial of service (system crash). In order to sucessfully

exploit this flaw, the attacker would need to know (or guess) some

aspects of the firewall ruleset in place on the target system to be able

to craft the right fragmented packets. (CAN-2005-0449)



The moxa char driver was missing a CAP_SYS_RAWIO check which could allow

a local user the ability to do things like replace the firmware.

(CAN-2005-0504)



A flaw when freeing a pointer in load_elf_library was discovered. A

local user could potentially use this flaw to cause a denial of service

(system crash). (CAN-2005-0749)



A flaw was discovered in the bluetooth driver system. On system where

the bluetooth modules are loaded, a local user could use this flaw to

gain elevated (root) privileges. (CAN-2005-0750)



Michal Zalewski discovered some flaws in the iso9660 filesystem. These

flaws could allow a malicious iso filesystem to cause a DoS or

potentially execute arbitrary code if mounted/examined. (CAN-2005-0815)



All users are advised to upgrade their kernels to the packages

associated with their machine architectures and configurations as listed

in this erratum.



Please note that the fix for CAN-2005-0449 required changing the

external symbol linkages (kernel module ABI) for the ip_defrag()

and ip_ct_gather_frags() functions. Any third-party module using either

of these would also need to be fixed.



4. Solution:



Before applying this update, make sure all previously released errata

relevant to your system have been applied.



To install kernel packages manually, use "rpm -ivh " and modify

system settings to boot the kernel you have installed. To do this, edit

/boot/grub/grub.conf and change the default entry to "default=0" (or, if

you have chosen to use LILO as your boot loader, edit /etc/lilo.conf and

run lilo)



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/docs for directions on how to

configure yum and apt-get.



Note that this may not automatically pull the new kernel in if you have

configured apt/yum to ignore kernels. If so, follow the manual

instructions above.

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



If you only wish to verify that each package has not been corrupted or

tampered with, examine only the sha1sum with the following command:
