Description

Dirk Heinrich reported that on Windows platforms when document.write() was called with a very long string a buffer overflow was caused in line breaking routines attempting to process the string for display. Such cases triggered an invalid read past the end of an array causing a crash which an attacker could potentially use to run arbitrary code on a victim's computer.
