tag_insight = "The kernel packages contain the Linux kernel, the core of any Linux
operating system.
* A buffer overflow flaw was found in the way the qeth_snmp_command()
function in the Linux kernel's QETH network device driver implementation
handled SNMP IOCTL requests with an out-of-bounds length. A local,
unprivileged user could use this flaw to crash the system or, potentially,
escalate their privileges on the system. (CVE-2013-6381, 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 Xen hypervisor implementation did not correctly
check privileges of hypercall attempts made by HVM guests, allowing
hypercalls to be invoked from protection rings 1 and 2 in addition to ring
0. A local attacker in an HVM guest able to execute code on privilege
levels 1 and 2 could potentially use this flaw to further escalate their
privileges in that guest. Note: Xen HVM guests running unmodified versions
of Red Hat Enterprise Linux and Microsoft Windows are not affected by this
issue because they are known to only use protection rings 0 (kernel) and 3
(userspace). (CVE-2013-4554, Moderate)
* A flaw was found in the way the Linux kernel's Adaptec RAID controller
(aacraid) checked permissions of compat IOCTLs. A local attacker could use
this flaw to bypass intended security restrictions. (CVE-2013-6383,
Moderate)
* It was found that, under specific circumstances, a combination of write
operations to write-combined memory and locked CPU instructions may cause a
core hang on certain AMD CPUs (for more information, refer to AMD CPU
erratum 793 linked in the References section). A privileged user in a guest
running under the Xen hypervisor could use this flaw to cause a denial of
service on the host system. This update adds a workaround to the Xen
hypervisor implementation, which mitigates the AMD CPU issue. Note: this
issue only affects AMD Family 16h Models 00h-0Fh Processors. Non-AMD CPUs
are not vulnerable. (CVE-2013-6885, Moderate)
* It was found that certain protocol handlers in the Linux kernel's
networking implementation could set the addr_len value without initializing
the associated data structure. A local, unprivileged user could use this
flaw to leak kernel stack memory to user space using the recvmsg, recvfrom,
and recvmmsg system calls. (CVE-2013-7263, Low)
* A flaw was found in the way the get_dumpable() func ...
