Debian Security Advisory DSA-2949-1 security@debian.org
http://www.debian.org/security/ Salvatore Bonaccorso
June 05, 2014 http://www.debian.org/security/faq
- - -------------------------------------------------------------------------
Package : linux
CVE ID : CVE-2014-3144 CVE-2014-3145 CVE-2014-3153
Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service or privilege escalation:
CVE-2014-3144 / CVE-2014-3145
A local user can cause a denial of service (system crash) via
crafted BPF instructions.
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.
For the stable distribution (wheezy), these problems have been fixed in
version 3.2.57-3+deb7u2.
For the unstable distribution (sid), these problems will be fixed soon.
We recommend that you upgrade your linux packages.
