A denial-of-service flaw was found in Quassel IRC, a distributed IRC client: This patch fixes two bugs. The first is garbage characters caused by accidentally splitting the string in the middle of a multibyte character. Since the new code splits at a character level instead of a byte level, this will no longer be an issue. The second is the core crash caused by sending an overlength CTCP query ("/me") containing only multibyte characters. This bug was caused by the old CTCP splitter using the byte index from lastParamOverrun() as a character index for a QString. https://github.com/quassel/quassel/commit/b5e38970ffd55e2dd9f706ce75af9a8d7730b1b8
