OpenSSL 0.9.8 < 0.9.8za Multiple Vulnerabilities

High Nessus Plugin ID 74363

Synopsis

The remote service is affected by multiple vulnerabilities.

Description

According to its banner, the remote web server uses a version of OpenSSL 0.9.8 prior to 0.9.8za. The OpenSSL library is, therefore, reportedly affected by the following vulnerabilities :

- 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 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

Upgrade to OpenSSL 0.9.8za or later.
