        Content of this advisory:
        1) security vulnerability resolved: imapd, ipop2d, ipop3d
           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

The eMail access daemons imapd(8), ipop2d(8) and ipop3d(8) of SuSE 6.1 are vulnerable to several buffer overflows. Due to a misconfiguration these vulnerbilities could be triggered remotely after a user had been authenticated.

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:

- joe (configuration file vulnerability): The problem has been reported on multiple security-related mailing lists. We are about to provide fixed packages.

- The game spaceboom (SVGA shoot'em up) has been found vulnerable to multiple vulnerabilities. As a reaction to these bugs, the spaceboom game has been dropped from the distribution. We recommend to deinstall the game from our 6.x and 7.x distribution by using the command `rpm -e space´, or to remove the suid bit from the file /usr/games/SpaceBoom/SpaceBoom using the command
`chmod -s /usr/games/SpaceBoom/SpaceBoom´.
(Note: removing the suid bit prevents the game from being used by non-root users and from being reinstalled after removal.)

- 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/man´ 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.

- A new nkitb/nkitserv package will be availabe soon. This update adresses bugs in timed, in.ftpd.

- New RPMs, that fix' a vulnerbility in the eperl package for SuSE 6.1-7.1 are currently being built.
