DESCRIPTION:
Multiple vulnerabilities have been reported in OpenTTD, which can be
exploited by malicious people to cause a DoS (Denial of Service) and
compromise a vulnerable system.

1) Errors within the processing of certain commands can be exploited
to e.g. cause a crash and potentially execute arbitrary code by
sending specially crafted commands.

2) An error within the processing of "NAME" chunks can be exploited
to cause a heap-based buffer overflow via specially crafted savegame
files.

3) An error within the processing of "PLYR" chunks can be exploited
to cause a heap-based buffer overflow via specially crafted savegame
files.

4) An error within the processing of "CHTS" chunks can be exploited
to cause a buffer overflow via specially crafted savegame files.

5) An error within the processing of "AIPL" chunks can be exploited
to cause a memory corruption via specially crafted savegame files.

6) An error within the processing of RLE compressed BMP images can be
exploited to cause a memory corruption via specially crafted BMP
files.

7) Errors within the handling memory allocations can be exploited to
e.g. cause buffer overflows via specially crafted BMP image files.

SOLUTION:
Fixed in the SVN repository. Update to version 1.1.3 when available.

PROVIDED AND/OR DISCOVERED BY:
Reported in OpenTTD bugs by Matt D. (monoid).
