Ezboard 2000 is a web based bulletin board system. It is available for Linux systems.
A vulnerability has been reported in some versions of Ezboard. In some CGI programs, user supplied data is written to a staticly sized array with a sprintf call. Large amounts of user supplied data may overflow this array and overwrite adjacent areas of stack memory. If return pointers are overwritten, arbitrary code may be executed as the vulnerable process.
It has been reported that the scripts ezboard.cgi, ezman.cgi and ezadmin.cgi suffer from this vulnerability.

A denial of service exists in the X11 font server shipped with RedHat Linux 6.x. Due to improper input validation, it is possible for any user to crash the X fontserver. This will prevent the X server from functioning properly.
Additional, similar problems exist in the stock xfs. Users can crash the font server remotely, and potential exists for buffer overruns. The crux of the problem stems from the font server being lax about verifying network input. While no exploits exist, it is likely they are available in private circles, and can result in remote root compromise.
