USN-2188-1: elfutils vulnerability

30 April 2014

elfutils vulnerability

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

  • Ubuntu 14.04 LTS
  • Ubuntu 13.10
  • Ubuntu 12.10

Summary

elfutils could be made to crash or run programs if it processed a specially crafted file.

Software Description

  • elfutils - collection of utilities to handle ELF objects

Details

Florian Weimer discovered that the elfutils libdw library incorrectly handled malformed compressed debug sections in ELF files. If a user or automated system were tricked into processing a specially crafted ELF file, applications linked against libdw could be made to crash, or possibly execute arbitrary code.

Update instructions

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

Ubuntu 14.04 LTS
libdw1 - 0.158-0ubuntu5.1
Ubuntu 13.10
libdw1 - 0.157-1ubuntu1.1
Ubuntu 12.10
libdw1 - 0.153-1ubuntu1.1

To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.

In general, a standard system update will make all the necessary changes.
