Please unblock package busybox. Last upload has one security bugfix
(CVE-2014-4607, #768945), the fix is from upstream stable branch,
fixing an integer overflow in lzo decompressor; it adds a Built-Using
control field for busybox-static variant (#768926), and also arranges
build system to only produce binary or indep .debs (or both), depending
on the d/rules target (binary-all vs binary-indep vs binary) -- this
is a long-standing lintian bug which I overlooked previously.
(The Built-Using field generation is a bit fun here: I asked on IRC
how people identify which libc is in use, and got various somewhat-
incpmplete replies (the prob is that on different arches, libc package
is named differently). So I invented my own way for busybox, because
this package allows me to do that -- I took the contents of $shlibs:Depends
variable for the dynamically-linked version, and transformed it into
a list of sources required for Built-Using using dpkg-query.
There's no code changes except the lzo decompression bugfix, only
packaging changes.
Thank you!
