As said on IRC, I have been pointed that the second patch actually breaks the breaks libnss/libnss-dns ABI. This means that the resolver might not work correctly if all the binaries using libnss are restarted. The same way there might be an issue on the d-i side if the libc in d-i and libnss-dns-udeb are out of sync. Therefore I'll do a new upload without the patch fixing CVE-2015-5180, leaving only the PowerPC fix. That should be either today or tomorrow. Sorry about this complication.
