OpenSSL < 0.9.8o / 1.0.0a Multiple Vulnerabilities

High Nessus Plugin ID 46801

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.

Synopsis

The remote web server has a SSL-related vulnerability.

Description

According to its banner, the remote web server is running a version of OpenSSL older than 0.9.8o / 1.0.0a. Such versions have the following vulnerabilities :

- The mishandling of Cryptographic Message Syntax structures containing an OriginatorInfo element can lead to data being written to invalid memory addresses or memory being freed up twice. (CVE-2010-0742)

- An uninitialized buffer of undefined length is returned when verification recovery fails for RSA keys. This allows an attacker to bypass key checks in applications calling the function EVP_PKEY_verify_recover(). Note this function is not used by OpenSSLcode itself. (CVE-2010-1633)

Solution

Upgrade to OpenSSL 0.9.8o / 1.0.0a or later.
