Details

An information leak in the Linux kernel was discovered that could leak the
high 16 bits of the kernel stack address on 32-bit Kernel Virtual Machine
(KVM) paravirt guests. A user in the guest OS could exploit this leak to
obtain information that could potentially be used to aid in attacking the
kernel. (CVE-2014-8134)

A flaw in the handling of malformed ASCONF chunks by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel was discovered. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-3673)

A flaw in the handling of duplicate ASCONF chunks by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel was discovered. A
remote attacker could exploit this flaw to cause a denial of service
(panic). (CVE-2014-3687)

It was discovered that excessive queuing by SCTP (Stream Control
Transmission Protocol) implementation in the Linux kernel can cause memory
pressure. A remote attacker could exploit this flaw to cause a denial of
service. (CVE-2014-3688)

A null pointer dereference flaw was discovered in the the Linux kernel’s
SCTP implementation when ASCONF is used. A remote attacker could exploit
this flaw to cause a denial of service (system crash) via a malformed INIT
chunk. (CVE-2014-7841)

Jouni Malinen reported a flaw in the handling of fragmentation in the
mac8Linux subsystem of the kernel. A remote attacker could exploit this
flaw to obtain potential sensitive cleartext information by reading
packets. (CVE-2014-8709)

A stack buffer overflow was discovered in the ioctl command handling for
the Technotrend/Hauppauge USB DEC devices driver. A local user could
exploit this flaw to cause a denial of service (system crash) or possibly
gain privileges. (CVE-2014-8884)

Andy Lutomirski discovered that the Linux kernel does not properly handle
faults associated with the Stack Segment (SS) register on the x86
architecture. A local attacker could exploit this flaw to cause a denial of
service (panic). (CVE-2014-9090)
