SUSE SLED12 / SLES12 Security Update : kernel (SUSE-SU-2015:0068-1)

high Nessus Plugin ID 83665


The remote SUSE host is missing one or more security updates.


The SUSE Linux Enterprise 12 kernel was updated to 3.12.31 to receive various security and bugfixes.

Security issues fixed: CVE-2014-9322: A local privilege escalation in the x86_64 32bit compatibility signal handling was fixed, which could be used by local attackers to crash the machine or execute code.

- CVE-2014-9090: Various issues in LDT handling in 32bit compatibility mode on the x86_64 platform were fixed, where local attackers could crash the machine.

- CVE-2014-8133: Insufficient validation of TLS register usage could leak information from the kernel stack to userspace.

- CVE-2014-7826: kernel/trace/trace_syscalls.c in the Linux kernel did not properly handle private syscall numbers during use of the ftrace subsystem, which allowed local users to gain privileges or cause a denial of service (invalid pointer dereference) via a crafted application.

- CVE-2014-3647: Nadav Amit reported that the KVM (Kernel Virtual Machine) mishandled noncanonical addresses when emulating instructions that change the rip (Instruction Pointer). A guest user with access to I/O or the MMIO could use this flaw to cause a denial of service (system crash) of the guest.

- CVE-2014-3611: A race condition flaw was found in the way the Linux kernel's KVM subsystem handled PIT (Programmable Interval Timer) emulation. A guest user who has access to the PIT I/O ports could use this flaw to crash the host.

- CVE-2014-3610: If the guest writes a noncanonical value to certain MSR registers, KVM will write that value to the MSR in the host context and a #GP will be raised leading to kernel panic. A privileged guest user could have used this flaw to crash the host.

- CVE-2014-7841: A remote attacker could have used a flaw in SCTP to crash the system by sending a maliciously prepared SCTP packet in order to trigger a NULL pointer dereference on the server.

- CVE-2014-3673: The SCTP implementation in the Linux kernel allowed remote attackers to cause a denial of service (system crash) via a malformed ASCONF chunk, related to net/sctp/sm_make_chunk.c and net/sctp/sm_statefuns.c.

- CVE-2014-3185: Multiple buffer overflows in the command_port_read_callback function in drivers/usb/serial/whiteheat.c in the Whiteheat USB Serial Driver in the Linux kernel allowed physically proximate attackers to execute arbitrary code or cause a denial of service (memory corruption and system crash) via a crafted device that provides a large amount of (1) EHCI or (2) XHCI data associated with a bulk response.
