USN-2374-1: Linux kernel vulnerabilities

9 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 versions:

Ubuntu 10.04 LTS
linux-image-2.6.32-67-386 - 2.6.32-67.134
linux-image-2.6.32-67-generic - 2.6.32-67.134
linux-image-2.6.32-67-generic-pae - 2.6.32-67.134
linux-image-2.6.32-67-ia64 - 2.6.32-67.134
linux-image-2.6.32-67-lpia - 2.6.32-67.134
linux-image-2.6.32-67-powerpc - 2.6.32-67.134
linux-image-2.6.32-67-powerpc-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-server - 2.6.32-67.134
linux-image-2.6.32-67-sparc64 - 2.6.32-67.134
linux-image-2.6.32-67-sparc64-smp - 2.6.32-67.134
linux-image-2.6.32-67-versatile - 2.6.32-67.134
linux-image-2.6.32-67-virtual - 2.6.32-67.134

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.
