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 is different from CVSS.

Synopsis

The remote AIX host has a version of Java SDK installed that is affected by multiple vulnerabilities.

Description

The version of Java SDK installed on the remote AIX host is affected by multiple vulnerabilities :

- The Global Security Kit (GSKit) contains a flaw due to improper restrictions of TLS state transitions. A man-in-the-middle attacker can exploit this to downgrade the security of a session to use EXPORT_RSA ciphers.
This allows the attacker to more easily break the encryption and monitor or tamper with the encrypted stream. (CVE-2015-0138)

- An unspecified flaw exists that allows an attacker to execute code running under a security manager with elevated privileges.(CVE-2015-0192)

- A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists due to the support of weak EXPORT_RSA cipher suites with keys less than or equal to 512 bits. A man-in-the-middle attacker may be able to downgrade the SSL/TLS connection to use EXPORT_RSA cipher suites which can be factored in a short amount of time, allowing the attacker to intercept and decrypt the traffic. (CVE-2015-0204)

- Multiple unspecified vulnerabilities exist in multiple Java subcomponents including 2D, Beans, Deployment, JCE, JSSE, and tools. (CVE-2015-0458, CVE-2015-0459, CVE-2015-0469, CVE-2015-0477, CVE-2015-0478, CVE-2015-0480, CVE-2015-0486, CVE-2015-0488, CVE-2015-0491)

- An unspecified flaw exists that allows a remote attacker to bypass permission checks and gain access to sensitive information. (CVE-2015-1914)

- An unspecified flaw exists due to the Socket Extension Provider's handling of TLS and SSL connections. A remote attacker can exploit this to cause a denial of service.
(CVE-2015-1916)

- A security feature bypass vulnerability exists, known as Bar Mitzvah, due to improper combination of state data with key data by the RC4 cipher algorithm during the initialization phase. A man-in-the-middle attacker can exploit this, via a brute-force attack using LSB values, to decrypt the traffic. (CVE-2015-2808)

Solution

Fixes are available by version and can be downloaded from the IBM AIX website.
