ghostscript regression

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

- Ubuntu 18.10
- Ubuntu 18.04 LTS
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS


USN-3831-1 introduced a regression in Ghostscript.

Software Description:
- ghostscript: PostScript and PDF interpreter


USN-3831-1 fixed vulnerabilities in Ghostscript. Ghostscript 9.26
introduced a regression when used with certain options. This update fixes
the problem.

Original advisory details:

 It was discovered that Ghostscript contained multiple security issues. 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 18.10:
  ghostscript                     9.26~dfsg+0-0ubuntu0.18.10.3
  libgs9                          9.26~dfsg+0-0ubuntu0.18.10.3

Ubuntu 18.04 LTS:
  ghostscript                     9.26~dfsg+0-0ubuntu0.18.04.3
  libgs9                          9.26~dfsg+0-0ubuntu0.18.04.3

Ubuntu 16.04 LTS:
  ghostscript                     9.26~dfsg+0-0ubuntu0.16.04.3
  libgs9                          9.26~dfsg+0-0ubuntu0.16.04.3

Ubuntu 14.04 LTS:
  ghostscript                     9.26~dfsg+0-0ubuntu0.14.04.3
  libgs9                          9.26~dfsg+0-0ubuntu0.14.04.3

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