CVEs: CVE-2017-1000251 CVE-2017-14489
Systems running Virtuozzo 4.7 or the OpenVZ RHEL 6 kernel can now use
Ksplice to patch against the latest Parallels Virtuozzo Containers 4.7
kernel security update, 2.6.32-042stab125.1.
INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack running Virtuozzo 4.7
or OpenVZ on RHEL 6 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-2017-1000251: Stack overflow in Bluetooth L2CAP config buffer.
Incorrectly parsing a Bluetooth L2CAP configuration buffer could allow
it to overwrite data on the stack, potentially allowing a remote
attacker to execute arbitrary code in the kernel.
* CVE-2017-14489: NULL pointer dereference in the SCSI transport layer.
A logic error when checking the bounds to be read from a netlink socket in
the SCSI could lead to a NULL pointer dereference. A local user could use
this flaw to cause a denial-of-service.
* Denial-of-service in the keys subsystem when reading negatively instantiated key.
A missing check when reading a negatively instantiated key could lead to
a kernel crash. A local user with the ability to read keys in the keys
subsystem could use this flaw to cause a denial-of-service or escalate
privileges.
