Synopsis: ELSA-2017-3605 can now be patched using Ksplice
CVEs: CVE-2016-10200 CVE-2016-6213 CVE-2016-9604 CVE-2017-7533 CVE-2017-9242

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle Linux Security Advisory, ELSA-2017-3605.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running UEKR4 4.1.12 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-2017-9242: Denial-of-service when using send syscall of IPV6 socket.

A missing check when sending messages over IPV6 sockets could lead to an
out-of-bound access. A local user could use this flaw to cause a
denial-of-service.


* CVE-2016-10200: Denial-of-service when creating L2TP sockets using concurrent thread.

A missing check when creating L2TP socket could lead to a use-after-free
if a concurrent thread modify socket's flag while creating it. An attacker
could use this flaw to cause a denial-of-service.


* CVE-2016-9604: Permission bypass when creating key using keyring subsystem.

A missing check when an user create a key beginning with '.' could lead
to a permission bypass. A local attacker could use this flaw to access
sensitive information.


* CVE-2017-7533: Privilege escalation in inotify during file rename.

A race condition in inotify when renaming a file can result in kernel
memory corruption. A local attacker could use this flaw to escalate
privileges.


* CVE-2016-6213: Denial-of-service when bind mounting filesystems.

A missing limit could cause an overflow of the mount table. A user with
mount permissions could cause a denial-of-service by bind mounting many
filesystems and overflowing the mount table.
