memory resource consumption by sending a large number of crafted requests.

It was discovered that OpenSSL did not properly handle certain server

a denial of service by sending a message containing a specially crafted
server certificate. (CVE-2009-1379)

It was discovered that OpenSSL did not properly handle a DTLS

attacker could cause a denial of service by sending a specially crafted
request. (CVE-2009-1386)
