Description :

It was discovered that OpenSSL did not limit the number of DTLS
records it would buffer when they arrived with a future epoch. A
remote attacker could cause a denial of service via memory resource
consumption by sending a large number of crafted requests.
(CVE-2009-1377)

It was discovered that OpenSSL did not properly free memory when
processing DTLS fragments. A remote attacker could cause a denial of
service via memory resource consumption by sending a large number of
crafted requests. (CVE-2009-1378)

It was discovered that OpenSSL did not properly handle certain server
certificates when processing DTLS packets. A remote DTLS server could
cause 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
ChangeCipherSpec packet when it occured before ClientHello. A remote
attacker could cause a denial of service by sending a specially
