[Bug 1441388] Re: numactl crashes with segfault

[Daniel Holbach]

I took the liberty to add a cdbs patch (as that's what the source
package is using), find the resulting debdiff here:
http://paste.ubuntu.com/10790767/

I uploaded it and it's sitting in the release team's review queue.

Title:
  numactl crashes with segfault

Status in numactl package in Ubuntu:
  Fix Committed

Bug description:
  numactl sometimes crashes when enumerating hardware:

  root at node1:~# numactl --hardware
  available: 648 nodes (0-647)
  Segmentation fault

  Further analysis shows that libnuma is using an uninitialised pointer,
  which value depends on program layout. When layout is sufficiently
  different, the pointer is non-NULL and the library parses the data
  pointed to as a bitmap, crashing.

  Therefore, it is possible to leverage this in an exploit.

  I have fixed the issue upstream:
