You have received a Security Announcement about traceroute already.
An update package in the 6.4-i386 tree got confused with an older version.
This older version file has been replaced by the new file under the old
name in order to prevent the installation of an older package without the
security fixes. I apologize.
Here is the corrected advisory:
-----BEGIN PGP SIGNED MESSAGE-----
______________________________________________________________________________
SuSE Security Announcement
Package: traceroute
Announcement-ID: SuSE-SA:2000:041
Date: Monday, October 16th, 2000 16:10 MEST
Affected SuSE versions: 6.0, 6.1, 6.2, 6.3, 6.4, 7.0
Vulnerability Type: local root compromise
Severity (1-10): 6
SuSE default package: yes
Other affected systems: Linux systems using the NANOG traceroute
Content of this advisory:
1) security vulnerability resolved: traceroute
problem description, discussion, solution and upgrade information
2) pending vulnerabilities, solutions, workarounds
3) standard appendix (further information)
______________________________________________________________________________
1) problem description, brief discussion, solution, upgrade information
The security problem in the traceroute program as shipped with SuSE
Linux distributions is completely different from the one reported on
security mailing lists a few days ago (`traceroute -g 1 -g 1') by
Pekka Savola <pekkas@netcore.fi>. SuSE distributions do not contain
this particular traceroute implementation.
The problem in our traceroute was discovered independently and reported
to us by H D Moore <hdm@secureaustin.com>. The problem in the
implementation of traceroute that we ship is a format string parsing
bug in a routine that can be used to terminate a line in traceroute's
output to easily embed the program in cgi scripts as used for web
frontends for traceroute.
Using a specially crafted sequence of characters on the commandline,
it is possile to trick the traceroute program into running arbitrary
code as root.
If you want to temporarily work around this security vulnerability,
you can disable traceroute for normal users by clearing the suid bit on
the file /usr/sbin/traceroute: chmod -s /usr/sbin/traceroute . Do not
forget to change the respective line in /etc/permissions to read:
/usr/sbin/traceroute root.root 755
We have prepared update packages on our ftp server that eliminate the
vulnerability in the traceroute program. Note that the traceroute program
is contained in the nkita or the nkitb package, depending on the
distribution version. Distributions starting with SuSE-6.4 contain the
traceroute program in the nkitb package which is not required by the
boot process and therefore counts as an additional package.
Download the update package from locations described below and install
the package with the command `rpm -Fhv file.rpm'. The md5sum for each
file is in the line below. You can verify the integrity of the rpm
files using the command
`rpm --checksig --nogpg file.rpm',
independently from the md5 signatures below.
