Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2014-5077: Remote denial-of-service in SCTP on simultaneous connections.

Linux kernel built with the support for Stream Control Transmission
Protocol is vulnerable to a NULL pointer dereference flaw. It could occur
when simultaneous new connections are initiated between the same pair of
hosts. A remote user/program could use this flaw to crash the system kernel
resulting in denial-of-service.


* CVE-2014-0203: Memory corruption on listing procfs symbolic links.

The symbolic link walking function didn't properly terminate it's return
value which could lead to excessive freeing of memory and consequent memory
corruption. A local, unprivileged user could use this flaw to crash the system.


* CVE-2014-4653: Use after free in ALSA card controls.

Missing synchronization in ALSA card controls could lead to a control
being freed while being in use.


* CVE-2014-4654, CVE-2014-4655: Missing validity checks in ALSA user controls.

Missing validity checks when replacing user controls could lead to an attempt
to free something that is not a user control or a control that is not owned
by the process. Userspace was also allowed to to bypass user control count
by overflowing it.


* CVE-2014-4656: ALSA Control ID overflow.

Missing range checks in ALSA control IDs could lead to an integer overflow.


* CVE-2014-4667: Denial-of-service in SCTP stack when unpacking a COOKIE_ECHO chunk.

Incorrect reference counting in the error path of sctp_unpack_cookie()
could corrupt the backlog reference counter, preventing any future SCTP
association. A remote attacker could use this flaw to cause a
denial-of-service.


* CVE-2014-4652: Arbitrary memory disclosure in ALSA user controls.

Lack of synchronization between reads and writes to ALSA user controls
could lead to a kernel memory disclosure.


* CVE-2014-4508: Denial-of-service in syscall audit code when using wrong syscall number.

A flaw in the error path of the entry point of a syscall leads to a kernel
panic if syscall auditing is enabled and the syscall number is larger than
the number of syscalls. A local, unprivileged user could use this flaw to
cause a denial-of-service.
