CVE-2016-6884
TLS cipher suites with CBC mode in TLS 1.1 and 1.2 in MatrixSSL before 3.8.3 allow remote attackers to cause a denial of service (out-of-bounds read) via a crafted message.
Does this matter?
Lower severity and a low EPSS score (1.33%). Track it; it rarely justifies an emergency change on its own.
