Package: dpkg
Version: 1.15.8
Severity: critical

dpkg_ar_member_put_header contains a buffer overflow that causes packages on
armel to be empty as an result.  This is entirely due to the calling convention
due to the stack being corrupted.  It seems that the outcome on other
architectures is not so severe, but it broke autobuilding heavily on armel due
to it generating broken packages *and* dpkg-deb succeeding.  The packages were
output onto fd 0 instead of fd 5 because the null byte was written into the
ar_fd register.

A patch is currently being tested.
