-----------------------------------------------------------------------
Immunix OS Security Advisory
Packages updated: sysklogd
Affected products: Immunix OS 6.2, 7.0-beta, and 7.0
Bugs fixed: immunix/1623
Date: Thu Jun 14 2001
Advisory ID: IMNX-2001-70-026-01
Author: Seth Arnold <sarnold@wirex.com>
-----------------------------------------------------------------------
Description:
The Linux kernel logging daemon klogd distributed in the sysklogd
package can be forced to quit if it receives a null byte in a log
message from the Linux kernel. These updates have applied a patch
from roessler at does-not-exist dot org to fix this problem.
Because an attacker would need to convince the kernel to log a null
byte in order to exploit this problem, we don't think it is an issue
for most sites; however, the bug was found when a kernel module
supplied with kernel 2.4 attempted to print a null byte.
We recommend Immunix OS users upgrade their sysklogd packages.
