+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
+ - i have started an lkml thread: http://lkml.org/lkml/2009/12/2/232, but it appears
+   that there is no longer any interest in the problems...
+ jmm> Disabled in 2.6.32-2
