McAfee Email Gateway OpenSSL Multiple Vulnerabilities (SB10075)

High Nessus Plugin ID 76579

Synopsis

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

Description

The remote host is running a version of McAfee Email Gateway (MEG) that is affected by the multiple vulnerabilities related to the included OpenSSL library :

- An error exists in the function 'ssl3_read_bytes' that can 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)

- An error exists related to the implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) that can allow nonce disclosure via the 'FLUSH+RELOAD' cache side-channel attack. (CVE-2014-0076)

- A buffer overflow error exists related to invalid DTLS fragment handling that can lead to 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 can 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 can 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 can 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 can allow denial of service attacks.
Note that this issue only affects OpenSSL TLS clients.
(CVE-2014-3470)
