Ubuntu 14.04 LTS : Linux kernel (Utopic HWE) vulnerabilities (USN-2467-1)

high Nessus Plugin ID 80514

Synopsis

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

Description

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2467-1 advisory.

- The sctp_process_param function in net/sctp/sm_make_chunk.c in the SCTP implementation in the Linux kernel before 3.17.4, when ASCONF is used, allows remote attackers to cause a denial of service (NULL pointer dereference and system crash) via a malformed INIT chunk. (CVE-2014-7841)

- Race condition in arch/x86/kvm/x86.c in the Linux kernel before 3.17.4 allows guest OS users to cause a denial of service (guest OS crash) via a crafted application that performs an MMIO transaction or a PIO transaction to trigger a guest userspace emulation error report, a similar issue to CVE-2010-5313.
(CVE-2014-7842)

- The __clear_user function in arch/arm64/lib/clear_user.S in the Linux kernel before 3.17.4 on the ARM64 platform allows local users to cause a denial of service (system crash) by reading one byte beyond a /dev/zero page boundary. (CVE-2014-7843)

- Stack-based buffer overflow in the ttusbdecfe_dvbs_diseqc_send_master_cmd function in drivers/media/usb/ttusb-dec/ttusbdecfe.c in the Linux kernel before 3.17.4 allows local users to cause a denial of service (system crash) or possibly gain privileges via a large message length in an ioctl call.
(CVE-2014-8884)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
