[Bug 1674532] Re: Ubuntu 14.04 broken during PXE boot

[Pieter Lexis]

This problem stems from the inclusion of the fix for CVE-2015-5180. The
internal number for A + AAAA changed in glibc (from T_UNSPEC=62321 to
T_QUERY_A_AND_AAAA=439963904).

In TCPDump, we see queries going out for TYPE62321 (the former internal
number for A+AAAA).

I think busybox uses the old symbols here?

Title:
  Ubuntu 14.04 broken during PXE boot

Status in eglibc package in Ubuntu:
  Confirmed

Bug description:
  After installing the libc6_2.19-0ubuntu6.10_amd64_udeb package during
  the automated install of ubuntu 14.04.5, the system was suddenly
  unable to resolve hostnames via dns. Installing -0ubuntu6.9 resolved
  the issue. Reinstalling -ubuntu6.10 broke the system again.

  I note that -ubuntu6.10 was recently added to the archive.

  I am currently unable to install Ubuntu 14.04.5.
