============================================================================ Ubuntu Security Notice USN-2377-1 October 09, 2014 linux-ti-omap4 vulnerabilities ============================================================================ A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 LTS Summary: Several security issues were fixed in the kernel. Software Description: - linux-ti-omap4: Linux kernel for OMAP4 Details: 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) 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) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 12.04 LTS: linux-image-3.2.0-1455-omap4 3.2.0-1455.75 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.
