Trustix Secure Linux Security Advisory #2004-0061
Package name: apache, kernel, sudo
Summary: Multiple vulnerabilities
Date: 2004-11-19
Affected versions: Trustix Secure Linux 1.5
Trustix Secure Linux 2.0
Trustix Secure Linux 2.1
Trustix Secure Linux 2.2
Trustix Operating System - Enterprise Server 2
- --------------------------------------------------------------------------
Package description:
apache:
Apache is a full featured web server that is freely available, and also
happens to be the most widely used.
kernel:
The kernel package contains the Linux kernel (vmlinuz), the core of your
Trustix Secure Linux operating system. The kernel handles the basic
functions of the operating system: memory allocation, process allocation,
device input and output, etc.
sudo:
Sudo (superuser do) allows a system administrator to give certain
users (or groups of users) the ability to run some (or all) commands
as root while logging all commands and arguments.
Problem description:
apache:
An issue was discovered where the field length limit was not enforced
for certain malicious requests. This could lead to a remote denial of
service attack.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2004-0942 to this issue.
kernel:
Fixes a number of errors in binfmt_elf and smbfs.
sudo:
Liam Helmer discovered an input validation flaw in sudo. When the
standard shell "bash" starts up, it searches the environment for
variables with a value beginning with "()". For each of these
variables a function with the same name is created, with the function
body filled in from the environment variable's value.
A malicious user with sudo access to a shell script that uses bash can
use this feature to substitute arbitrary commands for any
non-fully-qualified programs called from the script. Therefore this
flaw can lead to privilege escalation.
Martin Schulze informed us that our previous sudo update did not fix
this problem. This update does.
Action:
We recommend that all systems with this package installed be upgraded.
Please note that if you do not need the functionality provided by this
package, you may want to remove it from your system.
