Detail

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

Summary:

USN-3866-2 introduced a regression in Ghostscript.

Software Description: - ghostscript: PostScript and PDF interpreter

Details:

USN-3866-2 fixed a regression in Ghostscript. The Ghostscript update introduced a new regression that resulted in certain pages being printed with a blue background. This update fixes the problem.

Original advisory details:

Tavis Ormandy discovered that Ghostscript incorrectly handled certain
PostScript files. If a user or automated system were tricked into
processing a specially crafted file, a remote attacker could possibly use
this issue 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+0-0ubuntu0.18.10.7
libgs9 9.26~dfsg+0-0ubuntu0.18.10.7

Ubuntu 18.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.18.04.7
libgs9 9.26~dfsg+0-0ubuntu0.18.04.7

Ubuntu 16.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.16.04.7
libgs9 9.26~dfsg+0-0ubuntu0.16.04.7

Ubuntu 14.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.14.04.7
libgs9 9.26~dfsg+0-0ubuntu0.14.04.7

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