CVE-2013-0166 is a vulnerability of currently unknown severity. OpenSSL before 0.9.8y, 1.0.0 before 1.0.0k, and 1.0.1 before 1.0.1d does not properly perform signature verification for OCSP responses, which allows remote OCSP servers to cause a denial of service (NULL pointer dereference and application crash) via an invalid key.. EPSS estimates a 19.65% chance of exploitation in the next 30 days.
