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 SP3 kernel was updated to 4.4.120 to receive various security and bugfixes. The following security bugs were fixed :

- CVE-2017-13166: An elevation of privilege vulnerability in the v4l2 video driver. (bnc#1072865).

- CVE-2017-15951: The KEYS subsystem did not correctly synchronize the actions of updating versus finding a key in the 'negative' state to avoid a race condition, which allowed local users to cause a denial of service or possibly have unspecified other impact via crafted system calls (bnc#1062840 bnc#1065615).

- CVE-2017-16644: The hdpvr_probe function in drivers/media/usb/hdpvr/hdpvr-core.c allowed local users to cause a denial of service (improper error handling and system crash) or possibly have unspecified other impact via a crafted USB device (bnc#1067118).

- CVE-2017-16912: The 'get_pipe()' function (drivers/usb/usbip/stub_rx.c) allowed attackers to cause a denial of service (out-of-bounds read) via a specially crafted USB over IP packet (bnc#1078673).

- CVE-2017-16913: The 'stub_recv_cmd_submit()' function (drivers/usb/usbip/stub_rx.c) when handling CMD_SUBMIT packets allowed attackers to cause a denial of service (arbitrary memory allocation) via a specially crafted USB over IP packet (bnc#1078672).

- CVE-2017-17975: Use-after-free in the usbtv_probe function in drivers/media/usb/usbtv/usbtv-core.c allowed attackers to cause a denial of service (system crash) or possibly have unspecified other impact by triggering failure of audio registration, because a kfree of the usbtv data structure occurs during a usbtv_video_free call, but the usbtv_video_fail label's code attempts to both access and free this data structure (bnc#1074426).

- CVE-2017-18174: The amd_gpio_remove function in drivers/pinctrl/pinctrl-amd.c calls the pinctrl_unregister function, leading to a double free (bnc#1080533).

- CVE-2017-18208: The madvise_willneed function in mm/madvise.c allowed local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping (bnc#1083494).

- CVE-2018-1000026: A insufficient input validation vulnerability in bnx2x network card driver could result in DoS: Network card firmware assertion takes card off-line. This attack appear to be exploitable via An attacker on a must pass a very large, specially crafted packet to the bnx2x card. This can be done from an untrusted guest VM. (bnc#1079384).

- CVE-2018-8087: Memory leak in the hwsim_new_radio_nl function in drivers/net/wireless/mac80211_hwsim.c allowed local users to cause a denial of service (memory consumption) by triggering an out-of-array error case (bnc#1085053).

- CVE-2018-1068: Insufficient user provided offset checking in the ebtables compat code allowed local attackers to overwrite kernel memory and potentially execute code. (bsc#1085107)

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.
