[Ksplice-Fedora-25-updates] New Ksplice updates for Fedora 25 (FEDORA-2017-f519ebb3c4)

[Oracle Ksplice]

Synopsis: FEDORA-2017-f519ebb3c4 can now be patched using Ksplice
CVEs: CVE-2017-6074

Systems running Fedora 25 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2017-f519ebb3c4.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Fedora 25
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

* Denial-of-service when reading and writing from FUSE device.

A race-condition between concurrent read and write operations on a FUSE
device can crash the kernel, leading to denial-of-service.


* Denial-of-service in SCSI Generic driver.

A missing sanity-check when writing to generic SCSI device may lead to
kernel panic. An unprivileged user with write permission to /dev/sg can
exploit this to cause denial-of-service.


* Denial-of-service in Direct Rendering Manager (DRM) subsystem.

An inconsistent control flow when using multiple displays through Direct
Rendering Manager Display Port interface can cause kernel panic, leading
to denial-of-service.


* CVE-2017-6074: Denial-of-service when using IPV6_RECVPKTINFO socket option.

A logic error when using IPV6_RECVPKTINFO socket option could lead to a
use-after-free. A local user could use this flaw to cause a
denial-of-service.


* Denial-of-service in Siano TV receiver driver.

An incorrect use of DMA buffer on the stack when passing USB control
message to Siano USB TV driver could lead to a stack corruption since
CONFIG_VMAP_STACK is enabled. A local attacker could use this flaw to
cause a denial-of-service.
