Ubuntu Security Notice USN-2188-1

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

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