New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

The SUSE Linux Enterprise 12 SP1 kernel was updated to 3.12.59 to receive various security and bugfixes.

Main feature additions :

- Improved support for Clustered File System (CephFS, fate#318586).

- Addition of kGraft patches now produces logging messages to simplify auditing (fate#317827).

The following security bugs were fixed :

- CVE-2016-1583: Prevent the usage of mmap when the lower file system does not allow it. This could have lead to local privilege escalation when ecryptfs-utils was installed and /sbin/mount.ecryptfs_private was setuid (bsc#983143).

- CVE-2014-9717: fs/namespace.c in the Linux kernel processes MNT_DETACH umount2 system calls without verifying that the MNT_LOCKED flag is unset, which allowed local users to bypass intended access restrictions and navigate to filesystem locations beneath a mount by calling umount2 within a user namespace (bnc#928547).

- CVE-2016-2185: The ati_remote2_probe function in drivers/input/misc/ati_remote2.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#971124).

- CVE-2016-2186: The powermate_probe function in drivers/input/misc/powermate.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#970958).

- CVE-2016-2188: The iowarrior_probe function in drivers/usb/misc/iowarrior.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#970956).

- CVE-2016-2847: fs/pipe.c in the Linux kernel did not limit the amount of unread data in pipes, which allowed local users to cause a denial of service (memory consumption) by creating many pipes with non-default sizes (bsc#970948).

- CVE-2016-3134: The netfilter subsystem in the Linux kernel did not validate certain offset fields, which allowed local users to gain privileges or cause a denial of service (heap memory corruption) via an IPT_SO_SET_REPLACE setsockopt call (bnc#971126 971793).

- CVE-2016-3136: The mct_u232_msr_to_state function in drivers/usb/serial/mct_u232.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted USB device without two interrupt-in endpoint descriptors (bnc#970955).

- CVE-2016-3137: drivers/usb/serial/cypress_m8.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both an interrupt-in and an interrupt-out endpoint descriptor, related to the cypress_generic_port_probe and cypress_open functions (bnc#970970).

- CVE-2016-3138: The acm_probe function in drivers/usb/class/cdc-acm.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a USB device without both a control and a data endpoint descriptor (bnc#970911 970970).

- CVE-2016-3140: The digi_port_init function in drivers/usb/serial/digi_acceleport.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (NULL pointer dereference and system crash) via a crafted endpoints value in a USB device descriptor (bnc#970892).

- CVE-2016-3689: The ims_pcu_parse_cdc_data function in drivers/input/misc/ims-pcu.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (system crash) via a USB device without both a master and a slave interface (bnc#971628).

- CVE-2016-3951: Double free vulnerability in drivers/net/usb/cdc_ncm.c in the Linux kernel allowed physically proximate attackers to cause a denial of service (system crash) or possibly have unspecified other impact by inserting a USB device with an invalid USB descriptor (bnc#974418).

- CVE-2016-4482: Fixed information leak in devio (bnc#978401).

- CVE-2016-4486: Fixed information leak in rtnetlink ( bsc#978822).

- CVE-2016-4569: Fixed information leak in events via snd_timer_user_tinterrupt (bsc#979213).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
