SuSE Security Announcement
Package: cups
Announcement-ID: SuSE-SA:2001:05
Date: Monday, March 5th, 2001 13:10:13 MET
Affected SuSE versions: 7.1
Vulnerability Type: local/remote root compromise
Severity (1-10): 5
SuSE default package: no
Other affected systems: All UN*X-systems using cups < 1.1.6.
Content of this advisory:
1) security vulnerability resolved: cups
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
CUPS is an implementation of the Internet Printing Protocol (IPP)
and is used as an alternative to the lpr and LPRng packages. The
CUPS package aims to be a comprehensive printing solution for
UN*X-systems. In SuSE-7.1 distribution, the cups package is not
used by any configuration utilities unless the admin has decided
to configure the package manually. The cups package has been
introduced in the SuSE-7.1 distribution; enhanced support for
future releases of the SuSE Linux distribution is planned. A
SuSE-internal security audit conducted by Sebastian Krahmer and
Thomas Biege revealed several overflows as well as insecure file
handling. These bugs have been fixed by adding length-checks and
securing the file-access. For a temporary workaround, remove the
suid-bit from the 'lppasswd' program. Make sure nobody from
outside your network can access the CUPS-server running on port
631. Allowing access to this port from outside is a bad idea
regardless whether or not the used version is vulnerable.
No remote-exploits are known yet.
Download the update package from locations desribed below and install
the package with the command `rpm -Uhv 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.

2) Pending vulnerabilities in SuSE Distributions and Workarounds:
Effective Monday, March 19 2001, five weeks after the release of
the new SuSE-7.1 distribution, SuSE will discontinue support for
the SuSE-linux distributions SuSE-6.0 SuSE-6.1 and SuSE-6.2.
SuSE puts much effort into adding security improvements (patches)
to the software instead of publishing a new version; the same
program with a fix for a specific problem promises to work just
as reliable as the original version from the distribution,
whereas new versions introduce new functionality which changes
the behaviour. In some cases however, especially if the security
leak is based on problematic design decisions or when the fix(es)
are fairly large, the only reasonable fix for a security problem
is to update to a newer version of the software. These newer
versions tend to become incompatible with our older distribution
releases because of missing features in the operating system
environment. This forces us to focus on the distributions of a
newer release date.
The remaining distributions
SuSE-6.3,
SuSE-6.4,
SuSE-7.0 and
SuSE-7.1
for the Intel i386, AXP Alpha, SPARC as well as PPC Power PC
platforms will continue to be supported for a two-year period
after the release of the respective distribution.
