-Candidate: CVE-2004-2135
-Description:
- cryptoloop on Linux kernel 2.6.x, when used on certain file systems with a block 
- size 1024 or greater, has certain "IV computation" weaknesses that allow watermarked 
- files to be detected without decryption.

-Notes:
- jmm> IIRC there was some serious flaming about the different disk encryption systems,
- jmm> I'm not sure whether this has been addressed or how real it is
- jmm> Plus, cryptoloop is marked DEPRECATED for a long time IIRC
- jmm> It's not included in stock 2.4 kernels, but only available in kernel-patch-cryptoloop,
- jmm> which is only part of sid and hasn't been shipped with neither Woody nor Sarge, so
- jmm> I'm marking all these N/A 
- - i am 99% sure that these issues still affect the latest kernels
- - debian-installer only supports loop-aes and dm-crypt (i believe),
-   which are known to be not affected by these issues, so most users
-   are not affected
- - perhaps a solution would be to disable cryptoloop?
- - i have started an lkml thread: http://lkml.org/lkml/2009/12/2/232, but it appears
