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.
