CWE-264

Description

OpenSSL before 0.9.8l, and 0.9.8m through 1.x, does not properly restrict client-initiated renegotiation within the SSL and TLS protocols, which might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection, a different vulnerability than CVE-2011-5094. NOTE: it can also be argued that it is the responsibility of server deployments, not a security library, to prevent or limit renegotiation when it is inappropriate within a specific environment

Affected configurations

• openssl openssl 0.9.8m • openssl openssl 0.9.8n • openssl openssl 0.9.8o • openssl openssl 0.9.8p • openssl openssl 0.9.8r • openssl openssl 0.9.8s • openssl openssl 0.9.8t • openssl openssl 0.9.8u • openssl openssl 0.9.8v • openssl openssl 0.9.8w • openssl openssl 0.9.8x • openssl openssl (<= 0.9.8k)
