Description Josh Bressers 2010-09-03 15:50:19 UTC
Security researcher wushi of team509 reported a heap buffer overflow in
code routines responsible for transforming text runs. A page could be
constructed with a bidirectional text run which upon reflow could result in
an incorrect length being calculated for the run of text. When this value
is subsequently used to allocate memory for the text too small a buffer may
be created potentially resulting in a buffer overflow and the execution of
attacker controlled memory.
