USN-2377-1: Linux kernel (OMAP4) vulnerabilities

Ubuntu Security Notice USN-2377-1


9th October, 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 version:



Ubuntu 12.04 LTS:

linux-image-3.2.0-1455-omap4 3.2.0-1455.75


To update your system, please follow these instructions: http://bit.ly/1aJDvTw.


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.
