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.
