Info (http://en.wikipedia.org/wiki/Mobipocket):

Mobipocket SA is a French company incorporated in March 2000 which

produces Mobipocket Reader software, an E-Book reader for some PDAs,

phones and desktop operating systems.

The Mobipocket software package is free and consists of various

publishing and reading tools for PDA, Smartphones, cellular phones

and e-book devices (Symbian, Windows Mobile, Palm OS, webOS, Java ME,

BlackBerry, Psion, Kindle and iLiad).

Mobipocket.com was bought by Amazon.com in 2005.[1] Amazon's acquisition

was believed to be a result of Adobe Systems's announcement that it would

no longer sell its eBook packaging and serving software.[2]

An alpha release of the java-based version of the mobipocket reader was

made available for cellphones on June 30, 2008.[3] There is also a reader

for desktop computers running Microsoft Windows, which also works with

computers running Mac OS X and Linux using WINE.[4]

It has been widely reported that since Amazon's acquisition of Mobipocket,

software support, user support, and platform growth was ended. In December,

2011, it was reported that Amazon officially notified the book publishers

that it was ending support for Mobipocket.

RIP: Mobipocket 2000-2011, Mobipocket eBook Format Is Gone, et.al. The

status of Mobipocket DRM content previously purchased by users continues

to be unclear since currently no other ebook reader supports this propriety

DRM method.

PoC released as is, I have no time at the moment for further investigations

=============================================================================

Crafting a .chm file is possible to cause a stack based buffer overflow. In

the case of this PoC, registers at the moment of crash are as follow.

EAX 0012F6B8

ECX 000002D5

EDX 000003E3

EBX 00000000

As you can see, the content of EIP is just the value of the stack address

at 0x0012F6E8
