Vulnerability Type: local fileaccess problem
Severity (1-10): 2
SuSE default package: yes
Other affected systems: All UN*X systems using this package
Content of this advisory:
1) security vulnerability resolved: sgmltool
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 sgmltool programs ("sgml2html" and others) are used to convert
SGML-files into various other formats.
During operation, the underlying SGML perlmodule creates temporary files
in an insecure way. This allows attackers to destroy arbitrary files owned
by the user who invoked the sgmltool program. The problem has been fixed
by creating temporary files with the exclusive (O_EXCL) option upon
opening them.
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:
- Marcus Meissner (Caldera) found a bug in KDE 2.1.*'s kdesu program
which allows attackers to gather private information. This is due to
insecure local filehandling by the kdesu program. Please update to
the newest packages.
- minicom
format string vulnerabilities have been found in the minicom package.
If /usr/bin/minicom is installed suid, the vulnerability may be
exploited to gain elevated privileges. Please note that this is not
the case in SuSE distributions. If you decided to make /usr/bin/minicom
suid uucp or even suid root, please make sure that you grant access to
the execution of minicom to trusted users only.
- cfingerd
The package has been found vulnerable to a remotely exploitable
weakness. SuSE Linux distributions do not ship this version of
fingerd.
- webmin
Insecure handling of temporary files has been found in webmin, a
comprehensive administration webinterface. SuSE distributions do not
contain the webmin package and therefore are not vulnerable to the
found vulnerabilities by default. We urge administrators who use
webmin to upgrade to the latest version of webmin available.
- gnupg/gpg, openssl
Several weaknesses have been found in gnupg/gpg that can reduce the
strength of encrypted data. We will provide updates for the gnupg/gpg
package. The updates are currently being tested.
