OpenSSL 1.0.1 < 1.0.1d Multiple Vulnerabilities

Low Nessus Plugin ID 64534

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: 4.2

Synopsis

The remote host may be affected by multiple vulnerabilities.

Description

According to its banner, the remote web server is running a version of OpenSSL 1.0.1 prior to 1.0.1d. The OpenSSL library is, therefore, reportedly affected by the following vulnerabilities :

- An error exists related to AES-NI, TLS 1.1, TLS 1.2 and the handling of CBC ciphersuites that could allow denial of service attacks. Note that platforms and versions that do not support AES-NI, TLS 1.1, or TLS 1.2 are not affected. (CVE-2012-2686)

- An error exists related to the handling of OCSP response verification that could allow denial of service attacks.
(CVE-2013-0166)

- An error exists related to the SSL/TLS/DTLS protocols, CBC mode encryption and response time. An attacker could obtain plaintext contents of encrypted traffic via timing attacks. (CVE-2013-0169)

Solution

Upgrade to OpenSSL 1.0.1d or later.
