Details

Tavis Ormandy discovered multiple security issues in Ghostscript. If a user
or automated system were tricked into processing a specially crafted file,
a remote attacker could possibly use these issues 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 18.04

• ghostscript - 9.22~dfsg+1-0ubuntu1.2
• libgs9 - 9.22~dfsg+1-0ubuntu1.2

Ubuntu 16.04

• ghostscript - 9.18~dfsg~0-0ubuntu2.9
• libgs9 - 9.18~dfsg~0-0ubuntu2.9

Ubuntu 14.04

• ghostscript - 9.10~dfsg-0ubuntu10.13
• libgs9 - 9.10~dfsg-0ubuntu10.13

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