give feedback to debian-lts@lists.debian.org.

If you are not using openvz flavors, please still consider b+c :-):

[DSA 3093-1] linux security update

Package : linux
CVE ID : CVE-2014-7841 CVE-2014-8369 CVE-2014-8884 CVE-2014-9090

Several vulnerabilities have been discovered in the Linux kernel that
may lead to a denial of service or privilege escalation:

CVE-2014-7841

Liu Wei of Red Hat discovered that a SCTP server doing ASCONF will
panic on malformed INIT chunks by triggering a NULL pointer
dereference.

CVE-2014-8369

A flaw was discovered in the way iommu mapping failures were handled
in the kvm_iommu_map_pages() function in the Linux kernel. A guest
OS user could exploit this flaw to cause a denial of service (host
OS memory corruption) or possibly have other unspecified impact on
the host OS.

CVE-2014-8884

A stack-based buffer overflow flaw was discovered in the
TechnoTrend/Hauppauge DEC USB driver. A local user with write access
to the corresponding device could use this flaw to crash the kernel
or, potentially, elevate their privileges.

CVE-2014-9090

Andy Lutomirski discovered that the do_double_fault function in
arch/x86/kernel/traps.c in the Linux kernel did not properly handle
faults associated with the Stack Segment (SS) segment register,
which allows local users to cause a denial of service (panic).

For the stable distribution (wheezy), these problems have been fixed in
version 3.2.63-2+deb7u2. This update also includes fixes for regressions
introduced by previous updates.

For the unstable distribution (sid), these problems will be fixed soon
in version 3.16.7-ckt2-1.

We recommend that you upgrade your linux packages.

[DSA 3094-1] bind9 security update

- -------------------------------------------------------------------------
Debian Security Advisory DSA-3094-1 security@debian.org

- -------------------------------------------------------------------------

Package : bind9
CVE ID : CVE-2014-8500

It was discovered that BIND, a DNS server, is prone to a denial of
service vulnerability.
By making use of maliciously-constructed zones or a rogue server, an
attacker can exploit an oversight in the code BIND 9 uses to follow
delegations in the Domain Name Service, causing BIND to issue unlimited
queries in an attempt to follow the delegation.
This can lead to resource exhaustion and denial of service
(up to and including termination of the named server process.)

For the stable distribution (wheezy), this problem has been fixed in
version 1:9.8.4.dfsg.P1-6+nmu2+deb7u3.

For the upcoming stable distribution (jessie), this problem will be
fixed soon.

For the unstable distribution (sid), this problem will be fixed soon.

We recommend that you upgrade your bind9 packages.
