Ubuntu 14.04 LTS : Linux kernel vulnerabilities (USN-3655-1)

high Nessus Plugin ID 110050

Language:

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-3655-1 advisory.

 - The xen_biovec_phys_mergeable function in drivers/xen/biomerge.c in Xen might allow local OS guest users to corrupt block device data streams and consequently obtain sensitive memory information, cause a denial of service, or gain host OS privileges by leveraging incorrect block IO merge-ability calculation.
 (CVE-2017-12134)

 - An elevation of privilege vulnerability in the Upstream kernel bluez. Product: Android. Versions: Android kernel. Android ID: A-63527053. (CVE-2017-13220)

 - A information disclosure vulnerability in the Upstream kernel encrypted-keys. Product: Android. Versions:
 Android kernel. Android ID: A-70526974. (CVE-2017-13305)

 - The __netlink_deliver_tap_skb function in net/netlink/af_netlink.c in the Linux kernel through 4.14.4, when CONFIG_NLMON is enabled, does not restrict observations of Netlink messages to a single net namespace, which allows local users to obtain sensitive information by leveraging the CAP_NET_ADMIN capability to sniff an nlmon interface for all Netlink activity on the system. (CVE-2017-17449)

 - drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated. (CVE-2017-18079)

 - The dm_get_from_kobject function in drivers/md/dm.c in the Linux kernel before 4.14.3 allow local users to cause a denial of service (BUG) by leveraging a race condition with __dm_destroy during creation and removal of DM devices. (CVE-2017-18203)

 - The ocfs2_setattr function in fs/ocfs2/file.c in the Linux kernel before 4.14.2 allows local users to cause a denial of service (deadlock) via DIO requests. (CVE-2017-18204)

 - The madvise_willneed function in mm/madvise.c in the Linux kernel before 4.14.4 allows local users to cause a denial of service (infinite loop) by triggering use of MADVISE_WILLNEED for a DAX mapping.
 (CVE-2017-18208)

 - The __munlock_pagevec function in mm/mlock.c in the Linux kernel before 4.11.4 allows local users to cause a denial of service (NR_MLOCK accounting corruption) via crafted use of mlockall and munlockall system calls. (CVE-2017-18221)

 - Systems with microprocessors utilizing speculative execution and speculative execution of memory reads before the addresses of all prior memory writes are known may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka Speculative Store Bypass (SSB), Variant 4. (CVE-2018-3639)

 - Incorrect buffer length handling in the ncp_read_kernel function in fs/ncpfs/ncplib_kernel.c in the Linux kernel through 4.15.11, and in drivers/staging/ncpfs/ncplib_kernel.c in the Linux kernel 4.16-rc through 4.16-rc6, could be exploited by malicious NCPFS servers to crash the kernel or execute code.
 (CVE-2018-8822)

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.
