Amazon Linux AMI Security Advisory: ALAS-2016-666
Advisory Release Date: 2016-03-10 16:30 Pacific
An insecure temporary file use flaw was found in the way sos created certain sosreport files. A local attacker could possibly use this flaw to perform a symbolic link attack to reveal the contents of sosreport files, or in some cases modify arbitrary files and escalate their privileges on the system.
Run yum update sos to update your system.
