This update fixes the following security issues :
A flaw was found in the way the Linux kernel’s IPv6 implementation handled certain UDP packets when the UDP Fragmentation Offload (UFO) feature was enabled. A remote attacker could use this flaw to crash the system or, potentially, escalate their privileges on the system. (CVE-2013-4387, Important)
A flaw was found in the way the Linux kernel handled the creation of temporary IPv6 addresses. If the IPv6 privacy extension was enabled (/proc/sys/net/ipv6/conf/eth0/use_tempaddr set to ‘2’), an attacker on the local network could disable IPv6 temporary address generation, leading to a potential information disclosure. (CVE-2013-0343, Moderate)
A flaw was found in the way the Linux kernel handled HID (Human Interface Device) reports with an out-of-bounds Report ID. An attacker with physical access to the system could use this flaw to crash the system or, potentially, escalate their privileges on the system.
(CVE-2013-2888, Moderate)
An off-by-one flaw was found in the way the ANSI CPRNG implementation in the Linux kernel processed non-block size aligned requests. This could lead to random numbers being generated with less bits of entropy than expected when ANSI CPRNG was used. (CVE-2013-4345, Moderate)
It was found that the fix for CVE-2012-2375 released via SLSA-2012:1580 accidentally removed a check for small-sized result buffers. A local, unprivileged user with access to an NFSv4 mount with ACL support could use this flaw to crash the system or, potentially, escalate their privileges on the system . (CVE-2013-4591, Moderate)
A flaw was found in the way IOMMU memory mappings were handled when moving memory slots. A malicious user on a KVM host who has the ability to assign a device to a guest could use this flaw to crash the host.
(CVE-2013-4592, Moderate)
Heap-based buffer overflow flaws were found in the way the Zeroplus and Pantherlord/GreenAsia game controllers handled HID reports. An attacker with physical access to the system could use these flaws to crash the system or, potentially, escalate their privileges on the system.
(CVE-2013-2889, CVE-2013-2892, Moderate)
Two information leak flaws were found in the logical link control (LLC) implementation in the Linux kernel. A local, unprivileged user could use these flaws to leak kernel stack memory to user space. (CVE-2012-6542, CVE-2013-3231, Low)
A heap-based buffer overflow in the way the tg3 Ethernet driver parsed the vital product data (VPD) of devices could allow an attacker with physical access to a system to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1929, Low)
Information leak flaws in the Linux kernel could allow a privileged, local user to leak kernel memory to user space. (CVE-2012-6545, CVE-2013-1928, CVE-2013-2164, CVE-2013-2234, Low)
A format string flaw was found in the Linux kernel’s block layer. A privileged, local user could potentially use this flaw to escalate their privileges to kernel level (ring0). (CVE-2013-2851, Low)
The system must be rebooted for this update to take effect.
