USN-2374-1: Linux kernel vulnerabilities

Ubuntu Security Notice USN-2374-1

9th October, 2014

linux vulnerabilities

A security issue affects these releases of Ubuntu and its derivatives:

• Ubuntu 10.04 LTS

Summary

Several security issues were fixed in the kernel.

Software description

• linux - Linux kernel

Details

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)

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)

Update instructions

The problem can be corrected by updating your system to the following package version:

Ubuntu 10.04 LTS:

linux-image-2.6.32-67-powerpc 2.6.32-67.134

linux-image-2.6.32-67-386 2.6.32-67.134

linux-image-2.6.32-67-sparc64 2.6.32-67.134

linux-image-2.6.32-67-generic-pae 2.6.32-67.134

linux-image-2.6.32-67-preempt 2.6.32-67.134

linux-image-2.6.32-67-lpia 2.6.32-67.134

linux-image-2.6.32-67-sparc64-smp 2.6.32-67.134

linux-image-2.6.32-67-powerpc64-smp 2.6.32-67.134

linux-image-2.6.32-67-versatile 2.6.32-67.134

linux-image-2.6.32-67-generic 2.6.32-67.134

linux-image-2.6.32-67-virtual 2.6.32-67.134

linux-image-2.6.32-67-server 2.6.32-67.134

linux-image-2.6.32-67-powerpc-smp 2.6.32-67.134

linux-image-2.6.32-67-ia64 2.6.32-67.134

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.
