SuSE Security Announcement - syslogd (a1)
Package: syslogd-1.3.33 (a1)
Date: Thu Nov 18 14:00:29 CET 1999
Affected SuSE versions: 6.2 and 6.3
Vulnerability Type: local denial-of-service attack
SuSE default package: yes
Other affected systems: all Linux systems using the syslog daemon
______________________________________________________________________________
A security hole was discovered in the package mentioned above.
Please update as soon as possible or disable the service if you are using
this software on your SuSE Linux installation(s).
Other Linux distributions or operating systems might be affected as
well, please contact your vendor for information about this issue.
Please note, that that we provide this information on an "as-is" basis only.
There is no warranty whatsoever and no liability for any direct, indirect or
incidental damage arising from this information or the installation of

_____________________________________________________________________________
1. Problem Description
The syslogd server uses a Unix Domain stream socket (/dev/log) for receiving
local log messages via syslog(3).
Unix Domain stream sockets are non connection-less, that means, that
one process is needed to serve one client.
2. Impact
By opening alot of local syslog connections a user could stop the
system from responding.
3. Solution
Updated the package from our FTP server.
