A security issue affects these releases of Ubuntu and its derivatives:
Several security issues were fixed in the kernel.
Steven Vittitoe reported multiple stack buffer overflows in Linux kernel’s magicmouse HID driver. A physically proximate attacker could exploit this flaw to cause a denial of service (system crash) or possibly execute arbitrary code via specially crafted devices. (CVE-2014-3181)
A bounds check error was discovered in the driver for the Logitech Unifying receivers and devices. A physically proximate attacker could exploit this flaw to to cause a denial of service (invalid kfree) or to execute arbitrary code. (CVE-2014-3182)
Ben Hawkes reported some off by one errors for report descriptors in the Linux kernel’s HID stack. A physically proximate attacker could exploit these flaws to cause a denial of service (out-of-bounds write) via a specially crafted device. (CVE-2014-3184)
Several bounds check flaws allowing for buffer overflows were discovered in the Linux kernel’s Whiteheat USB serial driver. A physically proximate attacker could exploit these flaws to cause a denial of service (system crash) via a specially crafted device. (CVE-2014-3185)
Steven Vittitoe reported a buffer overflow in the Linux kernel’s PicoLCD HID device driver. A physically proximate attacker could exploit this flaw to cause a denial of service (system crash) or possibly execute arbitrary code via a specially craft device. (CVE-2014-3186)
A flaw was discovered in the Linux kernel’s UDF filesystem (used on some CD-ROMs and DVDs) when processing indirect ICBs. An attacker who can cause CD, DVD or image file with a specially crafted inode to be mounted can cause a denial of service (infinite loop or stack consumption). (CVE-2014-6410)
James Eckersall discovered a buffer overflow in the Ceph filesystem in the Linux kernel. A remote attacker could exploit this flaw to cause a denial of service (memory consumption and panic) or possibly have other unspecified impact via a long unencrypted auth ticket. (CVE-2014-6416)
James Eckersall discovered a flaw in the handling of memory allocation failures in the Ceph filesystem. A remote attacker could exploit this flaw to cause a denial of service (system crash) or possibly have unspecified other impact. (CVE-2014-6417)
James Eckersall discovered a flaw in how the Ceph filesystem validates auth replies. A remote attacker could exploit this flaw to cause a denial of service (system crash) or possibly have other unspecified impact. (CVE-2014-6418)
The problem can be corrected by updating your system to the following package versions:
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make all the necessary changes.
ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. If you use linux-restricted-modules, you have to update that package as well to get modules which work with the new kernel version. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-server, linux-powerpc), a standard system upgrade will automatically perform this as well.
