Systems running CloudLinux 6 can now use Ksplice to patch against the
latest CloudLinux 6 kernel update, 2.6.32-954.3.5.lve1.4.59.el6.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running CloudLinux 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-2016-8633: Buffer overflow in firewire net driver.

A logic error on incoming packets checks could lead to a rx buffer
overflow. A remote attacker could use this flaw to cause a
denial-of-service.


* CVE-2018-14634: Privilege escalation in ELF executables.

An integer overflow in the argument setup for a new ELF executable could
result in attacker controlled corruption of the user stack when
executing a SUID binary.  A local, unprivileged user could use this flaw
to gain superuser privileges.


* CVE-2017-1000365: Privilege escalation when performing exec.

A logic error allows an unprivileged local user to bypass argument and
environmental string size limits when performing an exec syscall. A
local user could use this flaw to bypass guard pages between the stack
and another mapping, leading to potential privilege escalation.


* Improved fix for CVE-2016-1583: Privilege escalation in eCryptfs.

Mounting eCryptfs over procfs could result in a stack overflow with deep
nesting allowing a local, unprivileged user to cause a
denial-of-service, or potentially escalate privileges.
