IBM DB2 9.7 < Fix Pack 11 Multiple Vulnerabilities (Bar Mitzvah) (FREAK) (TLS POODLE)

High Nessus Plugin ID 84828

Synopsis

The remote database server is affected by multiple vulnerabilities.

Description

According to its version, the installation of IBM DB2 9.7 running on the remote host is prior to Fix Pack 11. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability exists in the monitoring and audit features that occurs when handling a specially crafted command. An authenticated, remote attacker can exploit this to disclose sensitive information. (CVE-2014-0919)

- A flaw exists that is triggered during the handling of a specially crafted ALTER TABLE statement on an identity column. An authenticated, remote attacker can exploit this to cause the server to terminate, resulting in a denial of service condition. (CVE-2014-6209)

- A flaw exists that is triggered during the handling of multiple ALTER TABLE statements on the same column. An authenticated, remote attacker can exploit this to cause the server to terminate, resulting in a denial of service condition. (CVE-2014-6210)

- A man-in-the-middle (MitM) information disclosure vulnerability, known as POODLE, exists due to the TLS server not verifying block cipher padding when using a cipher suite that employs a block cipher such as AES and DES. The lack of padding checking can allow encrypted TLS traffic to be decrypted. This vulnerability could allow for the decryption of HTTPS traffic by an unauthorized third party. (CVE-2014-8730)

- A flaw exists that is triggered when handling a specially crafted XML query. An authenticated, remote attacker can exploit this to cause excessive consumption of CPU resources, resulting in a denial of service condition. (CVE-2014-8901)

- An unspecified error exists during the handling of SELECT statements with XML/XSLT functions that allows a remote attacker to gain access to arbitrary files.
(CVE-2014-8910)

- A security feature bypass vulnerability, known as FREAK (Factoring attack on RSA-EXPORT Keys), exists in the IBM Global Security Kit (GSKit) 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-2015-0138)

- A flaw exists in the LUW component when handling SQL statements with unspecified Scaler functions. A remote, authenticated attacker can exploit this to cause a denial of service. (CVE-2015-0157)

- A denial of service vulnerability exists when processing an ECParameters structure due to an infinite loop that occurs when a specified curve is over a malformed binary polynomial field. A remote attacker can exploit this to perform a denial of service against any system that processes public keys, certificate requests, or certificates. This includes TLS clients and TLS servers with client authentication enabled. (CVE-2015-1788)

- An information disclosure vulnerability exists in the automated maintenance feature. An attacker with elevated privileges, by manipulating a stored procedure, can exploit this issue to disclose arbitrary files owned by the DB2 fenced ID on UNIX/Linux or the administrator on Windows. (CVE-2015-1883)

- A flaw exists in the Data Movement feature when handling specially crafted queries. An authenticated, remote attacker can exploit this to delete database rows from a table without having the appropriate privileges.
(CVE-2015-1922)

- A flaw exists when handling SQL statements having unspecified LUW Scaler functions. An authenticated, remote attacker can exploit this to run arbitrary code, under the privileges of the DB2 instance owner, or to cause a denial of service. (CVE-2015-1935)

- 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)

- A denial of service vulnerability exists in the query compiler QGM due to improper handling of duplicate reloc entry queries. An authenticated, remote attacker can exploit this to crash the database.

- A denial of service vulnerability exists in the SQLEX_FIND_GROUP() function due to improper handling of group name results. An authenticated, remote attacker can exploit this to crash the database.

- A denial of service vulnerability exists in the query compiler QGM due to improper handling of DBCLOB column types. An authenticated, remote attacker can exploit this to crash the database.

- A denial of service vulnerability exists in the Relational Data Services component in the SQLRA_GET_SECT_INFO_BY_CURSOR_NAME() function due to improper handling of stored procedures. An authenticated, remote attacker can exploit this to crash the database.

Solution

Apply IBM DB2 version 9.7 Fix Pack 11 or later.
