Update instructions

After a standard system update you need to restart applications using PCRE, such as the Apache HTTP server and Nginx, to make all the necessary changes.

Learn more about how to get the fixes.

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

Ubuntu Release Package Version
15.10 wily libpcre3 –  2:8.35-7.1ubuntu1.3
14.04 trusty libpcre3 –  1:8.31-2ubuntu2.2
12.04 precise libpcre3 –  8.12-4ubuntu0.2
