SuSE Security Announcement
Package: cups
Announcement-ID: SuSE-SA:2002:005
Date: Saturday, Feb 23st 2002 09:10 MET
Affected SuSE versions: 7.1, 7.2, 7.3
Vulnerability Type: remote privilege escalation
Severity (1-10): 5
SuSE default package: no
Other affected systems: all systems running CUPS
Content of this advisory:
1) security vulnerability resolved: CUPS bufferoverflow in IPP
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 well known Common Unix Printing System (CUPS) was found vulnerable
to a buffer overflow in the Internet Printing Protocol (IPP) handling
code.
The buffer overflow could be exploited by a remote attacker as long as
their IP address is allowed to connect to the CUPS server.
Please download the update package for your distribution and verify its
integrity by the methods listed in section 3) of this announcement.
Then, install the package using the command "rpm -Fhv file.rpm" to apply
the update.
After updateing the packages run "rclpd restart" as root to start the
new daemon.

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
- squid
A heap overflow in squid's URL constructing functions is fixed and
new packages are currently being built.
- ucd-snmpd
The UCD snmpd contains various security releated bugs.
We are currently reviewing the code and available fixes to ensure
they all get fixed. Patches will be available as soon as possible.
It is strongly recommended to filter SNMP (TCP and UDP packets
with destination of port 161) traffic.
- hanterm/wmtv
The recently reported vulnerabilities in hanterm and wmtv do not
affect SuSE installations because they are not installed setuid
or setgid.
- cipe
We are about to prepare kernel update packages that fix a DoS
problem in the kernel modules for the cipe encrypted tunneling
software.
______________________________________________________________________________
3) standard appendix: authenticity verification, additional information
- Package authenticity verification:
SuSE update packages are available on many mirror ftp servers all over
the world. While this service is being considered valuable and important
to the free and open source software community, many users wish to be
sure about the origin of the package and its content before installing
the package. There are two verification methods that can be used
independently from each other to prove the authenticity of a downloaded
file or rpm package:
1) md5sums as provided in the (cryptographically signed) announcement.
2) using the internal gpg signatures of the rpm package.
1) execute the command
md5sum <name-of-the-file.rpm>
after you downloaded the file from a SuSE ftp server or its mirrors.
Then, compare the resulting md5sum with the one that is listed in the
announcement. Since the announcement containing the checksums is
cryptographically signed (usually using the key securityat_private),
the checksums show proof of the authenticity of the package.
We disrecommend to subscribe to security lists which cause the
email message containing the announcement to be modified so that
the signature does not match after transport through the mailing
list software.
Downsides: You must be able to verify the authenticity of the
announcement in the first place. If RPM packages are being rebuilt
and a new version of a package is published on the ftp server, all
md5 sums for the files are useless.
2) rpm package signatures provide an easy way to verify the authenticity
of an rpm package. Use the command
rpm -v --checksig <file.rpm>
to verify the signature of the package, where <file.rpm> is the
filename of the rpm package that you have downloaded. Of course,
package authenticity verification can only target an uninstalled rpm
package file.
Prerequisites:
a) gpg is installed
b) The package is signed using a certain key. The public part of this
key must be installed by the gpg program in the directory
~/.gnupg/ under the user's home directory who performs the
signature verification (usually root). You can import the key
that is used by SuSE in rpm packages for SuSE Linux by saving
this announcement to a file ("announcement.txt") and
running the command (do "su -" to be root):
gpg --batch; gpg < announcement.txt | gpg --import
SuSE Linux distributions version 7.1 and thereafter install the
key "buildat_private" upon installation or upgrade, provided that
the package gpg is installed. The file containing the public key
is placed at the toplevel directory of the first CD (pubring.gpg)
and at ftp://ftp.suse.com/pub/suse/pubring.gpg-build.suse.de .
- SuSE runs two security mailing lists to which any interested party may
subscribe:
suse-securityat_private
- general/linux/SuSE security discussion.
All SuSE security announcements are sent to this list.
To subscribe, send an email to
<suse-security-subscribeat_private>.
suse-security-announceat_private
- SuSE's announce-only mailing list.
Only SuSE's security annoucements are sent to this list.
To subscribe, send an email to
<suse-security-announce-subscribeat_private>.
For general information or the frequently asked questions (faq)
send mail to:
<suse-security-infoat_private> or
<suse-security-faqat_private> respectively.
