Title: IBM DB2 Prior to 8.1 Fixpack 18 Multiple Security Vulnerabilities

Severity: HIGH

Description:

IBM DB2 is a database manager.

The application is prone to multiple remote vulnerabilities:

1. A security-bypass issue occurs while handling the 'DAS' command. A local attacker can exploit this issue to gain unauthorized access.

2. A denial-of-service vulnerability in the 'DB2JDS' service occurs when handling crafted network packets. Specifically, the software fails to sufficiently validate data supplied as a string length when performing a UNICODE to ASCII string conversion. This issue affects the 'jdbcReadString()' function of the vulnerable service. A remote attacker can exploit this issue to crash the affected service.

3. An unspecified security issue can cause a UNIX-specific private memory leak.

Successful exploits of these issues may allow an attacker to bypass certain security restrictions or cause denial-of-service conditions.

These issues affect versions prior to IBM DB2 8 FixPak 18.
