Synopsis :

The remote host is affected by multiple vulnerabilities related to
OpenSSL.

Description :

The firmware of the remote Fortinet host is running a version of
OpenSSL that is affected by one or more of the following
vulnerabilities :

- 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
this issue is only exploitable 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 execution of
arbitrary code. Note this issue only affects OpenSSL
when used as a DTLS client or server. (CVE-2014-0195)

- An error exists related to DTLS handshake handling that
could lead to denial of service attacks. Note 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 this issue only affects OpenSSL TLS
clients. (CVE-2014-3470)
