SERVER-OTHER -- Snort has detected traffic exploiting vulnerabilities in a server in the network.
SERVER-OTHER OpenSSL DTLS SRTP extension parsing denial-of-service attempt
Memory leak in d1_srtp.c in the DTLS SRTP extension in OpenSSL 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted handshake message. Impact: CVSS base score 7.1 CVSS impact score 6.9 CVSS exploitability score 8.6 confidentialityImpact NONE integrityImpact NONE availabilityImpact NONE Details: Ease of Attack:
This rule will alert when an attempt to exploit a known denial-of-service condition in OpenSSL. By sending multiple specially-crafted handshake messages, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server.

Denial of Service
Denial of Service attacks aim to make a server or program unresponsive for users. These attacks may be volume-based, to overwhelm the system, or they may use certain logical flaws in the software to cut the service off from the users. The attack may come from one or multiple sources. These attacks do not usually lead to a remote code execution. Volume based attacks are best handled using a firewall application.
