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

- Ubuntu 17.04
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

zziplib could be made to crash or run programs as your login if it opened a
specially crafted file.

Software Description:
- zziplib: library providing read access on ZIP-archives

Details:

Agostino Sarubbo discovered that zziplib incorrectly handled certain
malformed ZIP files. If a user or automated system were tricked into
opening a specially crafted ZIP file, a remote attacker could cause zziplib
to crash, resulting in a denial of service, or possibly execute arbitrary
code.

Update instructions:

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

Ubuntu 17.04:
  libzzip-0-13                    0.13.62-3ubuntu0.17.04.1

Ubuntu 16.10:
  libzzip-0-13                    0.13.62-3ubuntu0.16.10.1

Ubuntu 16.04 LTS:
  libzzip-0-13                    0.13.62-3ubuntu0.16.04.1

Ubuntu 14.04 LTS:
  libzzip-0-13                    0.13.62-2ubuntu0.1

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