ghostscript vulnerabilities

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

- Ubuntu 21.10
- Ubuntu 21.04
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS


Several security issues were fixed in Ghostscript.

Software Description:
- ghostscript: PostScript and PDF interpreter


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
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 21.10:
ghostscript 9.54.0~dfsg1-0ubuntu2.1
libgs9 9.54.0~dfsg1-0ubuntu2.1

Ubuntu 21.04:
ghostscript 9.53.3~dfsg-7ubuntu0.2
libgs9 9.53.3~dfsg-7ubuntu0.2

Ubuntu 20.04 LTS:

ghostscript 9.26~dfsg+0-0ubuntu0.18.04.15
libgs9 9.26~dfsg+0-0ubuntu0.18.04.15
