McAfee Web Gateway Multiple OpenSSL Vulnerabilities (SB10075)

Medium Nessus Plugin ID 76146

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.

VPR Score: 8.5

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The remote host is running a version of McAfee Web Gateway (MWG) that is affected by multiple vulnerabilities due to flaws in the OpenSSL library :

- 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)

- An error exists related to the implementation of the Elliptic Curve Digital Signature Algorithm (ECDSA) that could 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 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 in the function 'do_ssl3_write' that could allow a NULL pointer to be dereferenced leading to denial of service attacks. Note this issue is exploitable only if 'SSL_MODE_RELEASE_BUFFERS' is enabled. (CVE-2014-0198)

- 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 ciphersuites that could allow denial of service attacks. Note this issue only affects OpenSSL TLS clients. (CVE-2014-3470)

Solution

Apply the relevant patch per the vendor advisory.
