1) problem description, brief discussion, solution, upgrade information
A bug in joe(1), a userfriendly text editor, was found by Christer Öberg
of Wkit Security AB a few weeks ago.
After starting joe(1) it tries to open its configuration file joerc in the
current directory, the users home directory and some other locations.
joe(1) doesn't check the ownership of joerc when trying the current
directory.
An attacker could place a malicious joerc file in a public writeable
directory, like /tmp, to execute commands with the privilege of any user
(including root), which runs joe while being in this directory.
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:
- We are in the process of preparing update packages for the man package
which has been found vulnerable to a commandline format string bug.
The man command is installed suid man on SuSE systems. When exploited,
the bug can be used to install a different man binary to introduce a
trojan into the system. As an interim workaround, we recommend to
`chmod -s /usr/bin/manŽ and ignore the warnings and errors when
viewing manpages.
- The file browser MidnightCommander (mc) is vulnerable to unwanted
program execution. Updates are currently being built.
- Two bugs were found in the text editor vim. These bugs are currently
being fixed.
- A bufferoverflow in sudo was discovered and fixed RPMs will be available
as soon as possible. A exploit was not made public until now.
