Memory corruption when Adobe Shockwave Player parses .dir media file


Adobe Shockwave Player is the Adobe plugin to many different browsers
to view rich-media content on the web including animations,
interactive presentations, and online entertainment.

Adobe Shockwave Player does not properly parse .dir media file, which
causes a corruption in module DPLib by opening a malformed file with
an invalid value located in PoC repro02.dir at offset 0x36A4.

This problem was confirmed in the following versions of Adobe
Shockwave Player and MacOS X, other versions may be also affected.

Shockwave Player version 11.6.3r633, Module DPLib.framework on MacOS X
10.7.2 (11C74)
