CVE-2016-6306
The certificate parser in OpenSSL before 1.0.1u and 1.0.2 before 1.0.2i might allow remote attackers to cause a denial of service (out-of-bounds read) via crafted certificate operations, related to s3_clnt.c and s3_srvr.c.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 41.7%, higher than 99% of all known CVEs. Patch or mitigate before the next change window.
