CVE-2016-2106
Integer overflow in the EVP_EncryptUpdate function in crypto/evp/evp_enc.c in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h allows remote attackers to cause a denial of service (heap memory corruption) via a large amount of data.
Does this matter?
EPSS puts the probability of exploitation in the next 30 days at 27.3%, higher than 98% of all known CVEs. Patch or mitigate before the next change window.
