Notes:

- Reproduces on Adobe Reader X (10.1.12) and Adobe Reader XI (11.0.09) for 
Windows, on Windows 7, with Application Verifier enabled.

- The “ESI” register points into a heap boundary of a region of size 
0x5c000.

- The crash occurs approximately at the first iteration of a loop, which should 
normally iterate three times.

- Based on the type of memory reference causing the crash, we can assume it is 
a heap based buffer overflow.

- Attached samples: signal_sigsegv_f6529e93_1074_172.pdf (crashing file), 
172.pdf (original file).

This bug is subject to a 90 day disclosure deadline. If 90 days elapse without 
a broadly available patch, then the bug report will automatically become 
visible to the public.
