Ubuntu Security Notice USN-3915-1
March 21, 2019

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

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:

Several security issues were fixed in Ghostscript.

Software Description:
– ghostscript: PostScript and PDF interpreter

Details:

It was 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+0-0ubuntu0.18.10.8
libgs9 9.26~dfsg+0-0ubuntu0.18.10.8

Ubuntu 18.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.18.04.8

Ubuntu 16.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.16.04.8

Ubuntu 14.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.14.04.8
libgs9 9.26~dfsg+0-0ubuntu0.14.04.8

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