Description
* A NULL pointer dereference flaw was found in the way the Linux kernel's
Stream Control Transmission Protocol (SCTP) implementation handled
simultaneous connections between the same hosts. A remote attacker could
use this flaw to crash the system. (CVE-2014-5077, Important)
* An integer overflow flaw was found in the way the Linux kernel's Frame
Buffer device implementation mapped kernel memory to user space via the
mmap syscall. A local user able to access a frame buffer device file
(/dev/fb*) could possibly use this flaw to escalate their privileges on the
system. (CVE-2013-2596, Important)
* A flaw was found in the way the ipc_rcu_putref() function in the Linux
kernel's IPC implementation handled reference counter decrementing.
A local, unprivileged user could use this flaw to trigger an Out of Memory
(OOM) condition and, potentially, crash the system. (CVE-2013-4483,
Moderate)
* It was found that the permission checks performed by the Linux kernel
when a netlink message was received were not sufficient. A local,
unprivileged user could potentially bypass these restrictions by passing a
netlink socket as stdout or stderr to a more privileged process and
altering the output of this process. (CVE-2014-0181, Moderate)
* It was found that the try_to_unmap_cluster() function in the Linux
kernel's Memory Managment subsystem did not properly handle page locking in
certain cases, which could potentially trigger the BUG_ON() macro in the
mlock_vma_page() function. A local, unprivileged user could use this flaw
to crash the system. (CVE-2014-3122, Moderate)
* A flaw was found in the way the Linux kernel's kvm_iommu_map_pages()
function handled IOMMU mapping failures. A privileged user in a guest with
an assigned host device could use this flaw to crash the host.
(CVE-2014-3601, Moderate)
* Multiple use-after-free flaws were found in the way the Linux kernel's
Advanced Linux Sound Architecture (ALSA) implementation handled user
controls. A local, privileged user could use either of these flaws to crash
the system. (CVE-2014-4653, CVE-2014-4654, CVE-2014-4655, Moderate)
* A flaw was found in the way the Linux kernel's VFS subsystem handled
reference counting when performing unmount operations on symbolic links.
A local, unprivileged user could use this flaw to exhaust all available
memory on the system or, potentially, trigger a use-after-free error,
resulting in a system crash or privilege escalation. (CVE-2014-5045,
Moderate)
* An integer overflow flaw was found in the way the lzo1x_decompress_safe()
function of the Linux kernel's LZO implementation processed Literal Runs.
A local attacker could, in extremely rare cases, use this flaw to crash the
system or, potentially, escalate their privileges on the system.
(CVE-2014-4608, Low)
