The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-2932-1 advisory.

  • The Linux kernel before 4.4.1 allows local users to bypass file-descriptor limits and cause a denial of service (memory consumption) by sending each descriptor over a UNIX socket before closing it, related to net/unix/af_unix.c and net/unix/garbage.c. (CVE-2013-4312)

  • The clie_5_attach function in drivers/usb/serial/visor.c in the Linux kernel through 4.4.1 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a bulk-out endpoint.
    (CVE-2015-7566)

  • The usbvision driver in the Linux kernel package 3.10.0-123.20.1.el7 through 3.10.0-229.14.1.el7 in Red Hat Enterprise Linux (RHEL) 7.1 allows physically proximate attackers to cause a denial of service (panic) via a nonzero bInterfaceNumber value in a USB device descriptor. (CVE-2015-7833)

  • net/sctp/sm_sideeffect.c in the Linux kernel before 4.3 does not properly manage the relationship between a lock and a socket, which allows local users to cause a denial of service (deadlock) via a crafted sctp_accept call. (CVE-2015-8767)

  • Race condition in the tty_ioctl function in drivers/tty/tty_io.c in the Linux kernel through 4.4.1 allows local users to obtain sensitive information from kernel memory or cause a denial of service (use-after- free and system crash) by making a TIOCGETD ioctl call during processing of a TIOCSETD ioctl call.
    (CVE-2016-0723)

  • Race condition in arch/x86/mm/tlb.c in the Linux kernel before 4.4.1 allows local users to gain privileges by triggering access to a paging structure by a different CPU. (CVE-2016-2069)

  • Double free vulnerability in the snd_usbmidi_create function in sound/usb/midi.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (panic) or possibly have unspecified other impact via vectors involving an invalid USB descriptor. (CVE-2016-2384)

  • The snd_seq_ioctl_remove_events function in sound/core/seq/seq_clientmgr.c in the Linux kernel before 4.4.1 does not verify FIFO assignment before proceeding with FIFO clearing, which allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a crafted ioctl call. (CVE-2016-2543)

  • Race condition in the queue_delete function in sound/core/seq/seq_queue.c in the Linux kernel before 4.4.1 allows local users to cause a denial of service (use-after-free and system crash) by making an ioctl call at a certain time. (CVE-2016-2544)

  • The snd_timer_interrupt function in sound/core/timer.c in the Linux kernel before 4.4.1 does not properly maintain a certain linked list, which allows local users to cause a denial of service (race condition and system crash) via a crafted ioctl call. (CVE-2016-2545)

  • sound/core/timer.c in the Linux kernel before 4.4.1 uses an incorrect type of mutex, which allows local users to cause a denial of service (race condition, use-after-free, and system crash) via a crafted ioctl call. (CVE-2016-2546)

  • sound/core/timer.c in the Linux kernel before 4.4.1 employs a locking approach that does not consider slave timer instances, which allows local users to cause a denial of service (race condition, use-after- free, and system crash) via a crafted ioctl call. (CVE-2016-2547)

  • sound/core/timer.c in the Linux kernel before 4.4.1 retains certain linked lists after a close or stop action, which allows local users to cause a denial of service (system crash) via a crafted ioctl call, related to the (1) snd_timer_close and (2) _snd_timer_stop functions. (CVE-2016-2548)

  • sound/core/hrtimer.c in the Linux kernel before 4.4.1 does not prevent recursive callback access, which allows local users to cause a denial of service (deadlock) via a crafted ioctl call. (CVE-2016-2549)

  • The treo_attach function in drivers/usb/serial/visor.c in the Linux kernel before 4.5 allows physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by inserting a USB device that lacks a (1) bulk-in or (2) interrupt-in endpoint. (CVE-2016-2782)

  • The netfilter subsystem in the Linux kernel through 4.5.2 does not validate certain offset fields, which allows local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call. (CVE-2016-3134)

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