Ubuntu Security Notice USN-4469-1
August 24, 2020

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

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

- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
- Ubuntu 16.04 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 document
files. If a user or automated system were tricked into processing a
specially crafted file, a remote attacker could use this issue to cause
Ghostscript to crash, resulting in a denial of service, or possibly
execute arbitrary code.

Update instructions:

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

Ubuntu 20.04 LTS:
ghostscript 9.50~dfsg-5ubuntu4.2
libgs9 9.50~dfsg-5ubuntu4.2

Ubuntu 18.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.18.04.13
libgs9 9.26~dfsg+0-0ubuntu0.18.04.13

Ubuntu 16.04 LTS:
ghostscript 9.26~dfsg+0-0ubuntu0.16.04.13
libgs9 9.26~dfsg+0-0ubuntu0.16.04.13

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