[Pkg-cryptsetup-devel] Bug#438198: cryptsetup: Segfaults when specifying invalid device name to luksOpen

[Mario Iseli]

Package: cryptsetup
Version: 2:1.0.5-1
Severity: important

Hello Debian Cryptsetup Team,

I found the following bug:

aismis:~# cryptsetup luksOpen /dev/sda1 secret
Enter LUKS passphrase:
aismis:~# cryptsetup luksOpen /dev/bla1 secret
Segmentation fault

Program received signal SIGSEGV, Segmentation fault.
0xb7ea975e in memset () from /lib/i686/cmov/libc.so.6
(gdb) bt
#0  0xb7ea975e in memset () from /lib/i686/cmov/libc.so.6
#1  0x0804f917 in ?? ()

#5  0x0804bd15 in ?? ()
#6  0x00000000 in ?? ()

I think the trouble is more or less selfexplaining. :)

Thank you and regards...
