Amazon Linux 2 Security Advisory: ALAS-2018-987
Advisory Release Date: 2018-04-05 23:25 Pacific
Failure to handle errors when attempting to drop group privileges:
mod_wsgi before 4.2.4 for Apache, when creating a daemon process group, does not properly handle when group privileges cannot be dropped, which might allow attackers to gain privileges via unspecified vectors. (CVE-2014-8583 )
Run yum update mod_wsgi to update your system.
