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:

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 arbitra=
ry
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 9.25~dfsg+1-0ubuntu0.18.04.1
libgs9 9.25~dfsg+1-0ubuntu0.18.04.1

Ubuntu 16.04 LTS:
ghostscript 9.25~dfsg+1-0ubuntu0.16.04.1
libgs9 9.25~dfsg+1-0ubuntu0.16.04.1

Ubuntu 14.04 LTS:
ghostscript 9.25~dfsg+1-0ubuntu0.14.04.1
libgs9 9.25~dfsg+1-0ubuntu0.14.04.1

This update uses a new upstream release, which includes additional bug
fixes. In general, a standard system update will make all the necessary
changes.
