| Doc Text: |
A flaw was found in Apache Tomcat Native, which enabled several insecure OpenSSL options by default: ALLOW_CLIENT_RENEGOTIATION, NO_EXTENDED_MASTER_SECRET, IGNORE_UNEXPECTED_EOF, and ALLOW_NO_DHE_KEX. These defaults can weaken TLS protections. Apache Tomcat Native versions 1.3.0 through 1.3.8 and 2.0.0 through 2.0.15 are affected; the issue is fixed in versions 1.3.9 and 2.0.16.
