CVE-2014-2898
wolfSSL CyaSSL before 2.9.4 allows remote attackers to have unspecified impact via multiple calls to the CyaSSL_read function which triggers an out-of-bounds read when an error occurs, related to not checking the return code and MAC verification failure.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.77%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
