ghostscript vulnerabilities
==========================================================================

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

- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS

Summary:

Several security issues were fixed in Ghostscript.

Software Description:
- ghostscript: PostScript and PDF interpreter

Details:

Tavis Ormandy discovered multiple security issues in Ghostscript. If a user
or automated system were tricked into processing a specially crafted file,
a remote attacker could possibly use these issues to access arbitrary
files, execute arbitrary code, or cause a denial of service.

Update instructions:

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

Ubuntu 18.04 LTS:
  ghostscript                     9.22~dfsg+1-0ubuntu1.2
  libgs9                          9.22~dfsg+1-0ubuntu1.2

Ubuntu 16.04 LTS:
  ghostscript                     9.18~dfsg~0-0ubuntu2.9
  libgs9                          9.18~dfsg~0-0ubuntu2.9

Ubuntu 14.04 LTS:
  ghostscript                     9.10~dfsg-0ubuntu10.13
  libgs9                          9.10~dfsg-0ubuntu10.13

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