JBoss Web will enter into an infinite loop when a surrogate pair character is placed at the boundary of an internal buffer. A remote attacker could exploit this flaw to trigger a denial-of-service attack against a JBoss Web server that is hosting applications with UTF-8 character encoding enabled, or that will include user-supplied UTF-8 strings in a response.
