1)  problem description, brief discussion, solution, upgrade information

    The setuid application sudo(8) allows a user to execute commands under
    the privileges of another user (including root).
    sudo(8) previous to version 1.6.3p6 is vulnerable by a buffer overflow
    in it's logging code, which could lead to local root compromise.

    There is no exploit known to be public.
    A useful workaround isn't possible, the only fix is to install the new
    sudo packages.

    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:

    - New RPMs for HylaFax, a Fax Server, are currently being build, which
      fix a format bug in hfaxd, which could lead to local root privilege.

    - NEdit a GUI-style text editor needs an update due to a tmp race
      condition. The source code is currently being reviewed and new
      RPMs will be available within the next days.

    - Updated man RPMs will be available in a few days.

    - In the past weeks, some security related bugs in the Linux kernel 2.2
      and 2.4 were found. An announcement, that addresses this will be
      released this week.

    - Samba has serveral security problems, which could lead to local root
      access. Samba 2.0.8 fixes these problems. New RPMs are currently being
      build.
