Description Martin Prpič 2016-11-01 13:25:52 UTC

It was found that redis set weak permissions on certain files that could potentially contain sensitive information:

-rw-r--r--. 1 redis root 41599 Feb  8  2016 /etc/redis.conf
-rw-r--r--. 1 redis root  7355 Feb  8  2016 /etc/redis-sentinel.conf
drwxr-xr-x. 2 redis redis 4096 Sep  9 14:29 /var/lib/redis

This issue was originally reported in bug 1374700.

What's the recommended update? 640/750 ? Typically, things in /etc are world-readable?

I think 640 on the two files that contain passwords (redis.conf, redis-sentinel.conf) like is already done in the newer builds should be fine.
