New Ksplice updates for UEKR3 3.8.13 on OL6 and OL7 (ELSA-2018-4109)
Synopsis: ELSA-2018-4109 can now be patched using Ksplice
CVEs: CVE-2017-15299 CVE-2017-16532 CVE-2017-16537 CVE-2017-17448 CVE-2017-17558 CVE-2018-1068 CVE-2018-1093 CVE-2018-5332

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2018-4109.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR3 3.8.13 on
OL6 and OL7 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2018-5332: Out-of-bounds write when sending messages through Reliable Datagram Sockets.

A missing check when sending messages through Reliable Datagram Sockets
could lead to an out-of-bounds write in the heap. A local attacker could
use this flaw to cause a denial-of-service.

Orabug: 27934073


* CVE-2017-15299: Denial-of-service in uninstantiated key configuration.

A failure to check whether or not a key is instantiated before
performing operations on it can result in a NULL pointer dereference,
leading to a kernel crash. A local user could use this flaw to cause a
denial-of-service.

Orabug: 27913332


* CVE-2017-17448: Unprivileged access to netlink namespace creation.

net/netfilter/nfnetlink_cthelper.c in the Linux kernel through 4.14.4
does not require the CAP_NET_ADMIN capability for new, get, and del
operations, which allows local users to bypass intended access
restrictions because the nfnl_cthelper_list data structure is shared
across all net namespaces.

Orabug: 27898167


* CVE-2017-17558: Buffer overrun in USB core via integer overflow.

Failing to sanitize the bNumInterfaces field in a USB device descriptor
could allow a malicious device to induce a buffer overrun, potentially
causing a denial-of-service.

Orabug: 27898074


* CVE-2018-1093: Denial-of-service in ext4 bitmap block validity check.

A failure to correctly validate bitmap information from an ext4
filesystem can result in an out-of-bounds read, leading to a Kernel
crash. A local user with the ability to mount an ext4 filesystem could
use this flaw to cause a denial-of-service.

Orabug: 27854376


* NULL pointer dereference when using bind system call on RDS over Infiniband socket.

A logic error when using bind system call on RDS over Infiniband
instance could lead to a NULL pointer dereference. A local attacker
could use this flaw to cause a denial-of-service.

Orabug: 27843171


* CVE-2018-1068: Privilege escalation in bridging interface.

Lack of userspace parameter sanitization in the 32-bit syscall interface
for bridging allows a user with limited privilege to write into kernel
memory. This flaw could be exploited to escalate privilege.

Orabug: 27774015


* CVE-2017-16532: NULL pointer dereference when running USB tests with a crafted USB device.

A missing check when running USB tests with a USB device exposing
invalid endpoints configuration could lead to a NULL pointer dereference.
A local attacker could use this flaw to cause a denial-of-service.

Orabug: 27602324


* Out-of-bounds access in GTCO CalComp/InterWrite USB tablet HID parsing.

A validation failure when parsing a HID report from a GTCO
CalComp/InterWrite USB tablet can result in an out-of-bounds memory
access. A user with physical access to a system could use this flaw to
cause undefined behaviour or potentially escalate privileges.

Orabug: 27215090


* CVE-2017-16537: NULL pointer dereference when registering SoundGraph iMON Receiver and Display driver.

A missing check when registering SoundGraph iMON Receiver and Display
driver could lead to a NULL pointer dereference. A local attacker could
use this flaw to cause a denial-of-service.

Orabug: 27208380


* Improved fix to Spectre v2 hardening on context switch.

A missing NULL pointer check could result in a kernel crash when
removing a CPU from the system.

Orabug: 27699611


* IO stalls with FUSE filesystem lock contention.

Incorrect lock ordering in FUSE filesystems could result in a deadlock
and IO stalls or a system hang.

Orabug: 27760268


* Task hang in block device journalling layer fsync.

A transaction ID wraparound could cause a task hang when performing a
sync() operation on a filesystem using the JBD journalling layer under
IO load.

Orabug: 27842289
