                        SuSE Security Announcement

        Package:                uucp
        Announcement-ID:        SuSE-SA:2001:38
        Date:                   Wednesday, October 31th, 2001 15.06 MEST

                                of uucp

        Content of this advisory:
        1) security vulnerability resolved: uucp
           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

    UUCP is a well known tool suite for copying data between unix-like
    systems. Zen-Parse reported that the higher privileges of uux (UID
    uucp) aren't dropped if long options instead of normal (short) options
    are used. An attacker could exploit this hole, by specifying a malicious
    configuration file to execute and/or access arbitrary data with the
    privilege of user uucp.

    As a temporary fix, you could either uninstall uucp from your system,
    if not needed:
      - rpm -e uucp
    or remove the set[ug]id bit
      - chmod ug-s /usr/bin/uux

    Please, don't forget to add the permissions settings accordingly to
    your /etc/permissions.local file.


    Download the update package from locations described 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:

    - openssh
      After stabilizing the openssh package, updates for the distributions
      6.4-7.2 are currently being prepared. The update packages fix a security
      problem related to the recently discovered problems with source ip
      based access restrictions in a user's ~/.ssh/authorized_keys2 file.
      The packages will appear shortly on our ftp servers. Please note that
      packages for the distributions 6.3 and up including 7.0 containing
      cryptographic software are located on the German ftp server ftp.suse.de,
      all other packages can be found on ftp.suse.com at the usual location.
      We will issue a dedicated Security announcement for the openssh package.
