Synopsis:          Important: kernel security, bug fix, and enhancement update
Advisory ID:       SLSA-2015:1081-1
Issue Date:        2015-06-09
CVE Numbers:       CVE-2015-3331
                   CVE-2015-1805
                   CVE-2014-9420
                   CVE-2014-9419
                   CVE-2014-9585
--

* It was found that the Linux kernel's implementation of vectored pipe
read and write functionality did not take into account the I/O vectorsthat were already processed when retrying after a failed atomic access
operation, potentially resulting in memory corruption due to an I/O vector
array overrun. A local, unprivileged user could use this flaw to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2015-1805, Important)

* A buffer overflow flaw was found in the way the Linux kernel's Intel
AES-NI instructions optimized version of the RFC4106 GCM mode decryption
functionality handled fragmented packets. A remote attacker could use this
flaw to crash, or potentially escalate their privileges on, a system over
a connection with an active AES-GCM mode IPSec security association.
(CVE-2015-3331, Important)

* An information leak flaw was found in the way the Linux kernel changed
certain segment registers and thread-local storage (TLS) during a context
switch. A local, unprivileged user could use this flaw to leak the user
space TLS base address of an arbitrary process. (CVE-2014-9419, Low)

* It was found that the Linux kernel's ISO file system implementation did
not correctly limit the traversal of Rock Ridge extension Continuation
Entries (CE). An attacker with physical access to the system could use
this flaw to trigger an infinite loop in the kernel, resulting in a denial
of service. (CVE-2014-9420, Low)

* An information leak flaw was found in the way the Linux kernel's Virtual
Dynamic Shared Object (vDSO) implementation performed address
randomization. A local, unprivileged user could use this flaw to leak
kernel memory addresses to user-space. (CVE-2014-9585, Low)

The system must be rebooted for this update to take effect.
