"OpenTTD servers of version 0.6.1 and below are susceptible to a remotely exploitable buffer overflow when the server is filled with companies and clients with names that are (near) the maximum allowed length for names. In the worst case OpenTTD will write the following (mostly remotely changable bytes) into 1460 bytes of malloc-ed memory: up to 11 times (amount of players) 118 bytes up to 8 times (amount of companies) 124 bytes and 7 "header" bytes Resulting in up to 2297 bytes being written in 1460 bytes of malloc-ed memory. This makes it possible to remotely crash the game or change the gamestate into an unrecoverable state. " This is Debian bug #493714.
Use CVE-2008-3547 (to be updated later) for this issue, as reported. If Secunia wound up reporting a distinct bug, that would need an additional CVE. - Steve
