Many Fortinet products utilize OpenSSL and are affected by this advisory. Version 1, 2014-06-06 1500 PST: Initial advisory. Impact CVE-2014-0224 may allow an attacker with a privileged network position (man-in-the-middle) to decrypt SSL encrypted communications. CVE-2014-0221 may allow an attacker to crash a DTLS client with an invalid handshake. CVE-2014-0195 can result in a buffer overrun attack by sending invalid DTLS fragments to an OpenSSL DTLS client or server. CVE-2014-0198 and CVE-2010-5298 may allow an attacker to cause a denial of service under certain conditions, when SSL_MODE_RELEASE_BUFFERS is enabled. CVE-2014-3470 may allow an attacker to trigger a denial of service in SSL clients when anonymous ECDH ciphersuites are enabled. This issue does not affect Fortinet products. CVE-2014-0076 can be used to discover ECDSA nonces on multi-user systems by exploiting timing attacks in CPU L3 caches. This does not apply to Fortinet products. Affected Products FortiOS, FortiSwitch, FortiAnalyzer, FortiManager, FortiMail, FortiAP, FortiVoiceOS, FortiWeb, FortiAuthenticator, FortiDNS, FortiDDoS, FortiCache, FortiRecorder, FortiSandbox, FortiADC, FortiADC-E, Equalizer LX/GX, AscenLink Risk FortiOS 4.x and 5.x are affected by CVE-2014-0224 and CVE-2014-0195 (via CAPWAP service). In addition, FortiOS 5.x SSL VPN and HTTPS administration are vulnerable to CVE-2014-0198 and CVE-2010-5298. FortiAP is affected by CVE-2014-0224, CVE-2014-0221 and CVE-2014-0195. All other products listed in this advisory are only affected by CVE-2014-0224. Note that while the FortiVoice 200D, 2000E and VM products are affected, other FortiVoice products do not use OpenSSL and are not affected. This information may be subject to revision in future versions of this advisory. Solutions Workarounds FortiGuard labs has released an IPS signature entitled "OpenSSL.ChangeCipherSpec.Injection" to protect against CVE-2014-0224. This signature can be used on interface policies and transit policies to protect the FortiGate control plane and devices behind the FortiGate firewall, respectively. For more information on using IPS signatures, refer to the documentation. Customers running FortiGate firewalls who are not using CAPWAP protocol to support access points should consider disabling CAPWAP to reduce exposure to CVE-2014-0195. This can be performed in the Web UI on the interface configuration form, or using the CLI under "config system interface". Firmware Updates Fortinet is making every effort to produce software fixes for these vulnerabilities. Estimated availability times for these updates will be posted in future revisions of this advisory.
