Fedora 7 contains cryptsetup-luks 1.0-3. Using it can cause stack smashing
Steps to reproduce:
1. cryptsetup luksFormat -c aes-lrw-benbi -s 384 /dev/sda3
2. cryptsetup luksOpen /dev/sda3 enc
3. *** stack smashing detected ***: cryptsetup terminated
Updating to 1.0.5 resolved this issue. (You can also look at URL for original
NOTE: Since 1.0.5 release cryptsetup-luks becomes cryptsetup
FYI: In rawhide there is now cryptsetup 1.0.5.
in setup.c from 1.0.3 to 1.0.5 the following one line changed from
I guess this fixes the problem, because a backtrace shows the following:

Could you also push 1.0.5 to F7 update?
