New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

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)

Solution

Upgrade to a firmware version containing a fix for this vulnerability as referenced in the vendor advisory.
