Title:
numactl crashes with segfault
Status in numactl package in Ubuntu:
Fix Released
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:
