Debian Security Advisory 1386-2 – A problem has been discovered in the processing of chat messages. Overly long messages are truncated by the server to a fixed length, without paying attention to the multibyte characters. This leads to invalid UTF-8 on clients and causes an uncaught exception. Note that both wesnoth and the wesnoth server are affected. Note: This advisory only updates the MD5 sums for the stable distribution.
