medium Nessus Plugin ID 76493
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

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.
