Bug#142916: dpkg: can install a blatantly corrupt package
$ ar -x kernel-image-2.4.18-lsm_601_i386.deb
ar: kernel-image-2.4.18-lsm_601_i386.deb is not a valid archive
This package is corrupted by a few K. It installs without reporting any
errors, lilo gets run and installs an appropriate boot map, then at boot time
LILO reports a CRC error because the vmlinuz file is truncated!
This is wrong, even ar can tell it's a corrupt package, and dpkg should do
further checks and catch an error from gzip if it's CRC doesn't match!
This is a serious error, it can result in data loss when the files that are
installed don't match the correct contents of the package.
