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

- Ubuntu 14.10
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

unzip could be made to crash or run programs if it opened a specially
crafted file.

Software Description:
- unzip: De-archiver for .zip files

Details:

Wolfgang Ettlinger discovered that unzip incorrectly handled certain
malformed zip archives. If a user or automated system were tricked into
processing a specially crafted zip archive, an attacker could possibly
execute arbitrary code.

Update instructions:

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

Ubuntu 14.10:
  unzip                           6.0-12ubuntu1.1

Ubuntu 14.04 LTS:
  unzip                           6.0-9ubuntu1.1

Ubuntu 12.04 LTS:
  unzip                           6.0-4ubuntu2.1

Ubuntu 10.04 LTS:
  unzip                           6.0-1ubuntu0.1

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