Date: Thu, 5 Jun 2014 18:45:45 +0400 From: Solar Designer <solar@...nwall.com> To: oss-security@...ts.openwall.com Subject: Linux kernel futex local privilege escalation (CVE-2014-3153) Hi, This was handled via linux-distros, hence the mandatory oss-security posting. The issue was made public earlier today, and is included in this Debian advisory: https://lists.debian.org/debian-security-announce/2014/msg00130.html --- CVE-2014-3153 Pinkie Pie discovered an issue in the futex subsystem that allows a local user to gain ring 0 control via the futex syscall. An unprivileged user could use this flaw to crash the kernel (resulting in denial of service) or for privilege escalation. --- I've attached patches by Thomas Gleixner (four e-mails, in mbox format), as well as back-ports of those by John Johansen of Canonical, who wrote: --- For anyone who is interested I've attached back ports of the patches to 3.13 - minor conflicts in patch 4. It has applied cleanly back to 3.2 and 2.6.32 - conflict is in patches 3, and 4 --- Alexander Download attachment "futex.mbox" of type "application/mbox" (17348 bytes) Download attachment "patches-2.6.32.tgz" of type "application/octet-stream" (5098 bytes) Download attachment "patches-3.13.tgz" of type "application/octet-stream" (5120 bytes)
