Description Josh Bressers 2005-02-28 21:19:52 UTC

It is possible for a UTF8 string with invalid sequences to trigger a heap
overflow of converted Unicode data. Exploitability would depend on the attackers
ability to get the string into the buggy converter. General web content is
converted elsewhere but we can't rule out the possibility of a successful attack.
