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


Several security issues were fixed in Ghostscript.

Software Description:
– ghostscript: PostScript and PDF interpreter


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

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.
