Apache Tomcat 8.0.x < 8.0.11 Multiple OpenSSL Vulnerabilities

Synopsis :

The remote Apache Tomcat server is affected by multiple
vulnerabilities.

Description :

According to its self-reported version number, the Apache Tomcat
server running on the remote host is 8.0.x prior to 8.0.11. It is,
therefore, affected by multiple vulnerabilities in the bundled version
of OpenSSL :

- An error exists in the function 'ssl3_read_bytes' that
could allow data to be injected into other sessions or
allow denial of service attacks. Note that this issue
is exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is
enabled. (CVE-2010-5298)

- A buffer overflow error exists related to invalid DTLS
fragment handling that could lead to the execution of
arbitrary code. Note that this issue only affects
OpenSSL when used as a DTLS client or server.
(CVE-2014-0195)

- An error exists in the function 'do_ssl3_write' that
could allow a NULL pointer to be dereferenced leading to
denial of service attacks. Note that this issue is
exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is
enabled. (CVE-2014-0198)

- An error exists related to DTLS handshake handling that
could lead to denial of service attacks. Note that this
issue only affects OpenSSL when used as a DTLS client.
(CVE-2014-0221)

- An unspecified error exists that could allow an attacker
to cause usage of weak keying material leading to
simplified man-in-the-middle attacks. (CVE-2014-0224)

- An unspecified error exists related to anonymous ECDH
cipher suites that could allow denial of service
attacks. Note that this issue only affects OpenSSL TLS
clients. (CVE-2014-3470)

Note that Nessus has not attempted to exploit these issues but has
instead relied only on the application's self-reported version number.
