Public bug reported: numactl sometimes crashes when enumerating hardware:
root@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: https://github.com/numactl/numactl/commit/6a7c2cf3f00e32082a1ada300cc585740e2b4bbd ** Affects: numactl (Ubuntu) Importance: Undecided Status: New ** Information type changed from Private Security to Public -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to numactl in Ubuntu. https://bugs.launchpad.net/bugs/1441388 Title: numactl crashes with segfault To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/numactl/+bug/1441388/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
