1) problem description, brief discussion, solution, upgrade information
The Midnight Commander, mc(1), is a ncurses-based file manager.
A local attacker could trick mc(1) into executing commands with
the privileges of the user running mc(1) by creating malicious
directory names. This attack leads to local privilege escalation.
There does no workaround exist. The only solution is to update the
mc package.
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/manī and ignore the warnings and errors when
viewing manpages.
- 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.
- 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.
