Multiple vulnerabilities have been reported in IBM DB2 UDB, where some have unknown impacts, while others can be exploited by malicious, local users to gain escalated privileges, by malicious users to cause a DoS (Denial of Service) or to compromise a vulnerable system, and by malicious people to bypass certain security restrictions or to cause a DoS.
1) An error within the DB2PD tool when loading libraries can be exploited to execute arbitrary code with root privileges by setting the DB2INSTANCE environment variable.
2) An error within the Database Administration Server (DAS) can be exploited to cause a memory corruption by sending a specially crafted packet to default port 523/TCP.
3) A vulnerability within "SYSPROC.ADMIN_SP_C" can be exploited to compromise a vulnerable system.
For more information see vulnerability #2 in: SA29022
4) An unspecified vulnerability when executing "ALTER TABLE" statements can be exploited to bypass certain access restrictions.
5) The DB2DART tool executes the "TPUT" command and allows a user to execute commands as the DB2 instance owner.
6) Unspecified errors exist in DB2WATCH, DB2FREEZE, and within several setuid binaries. No further information is available.
7) Unspecified errors within the processing of SQLJRA packets can be exploited to cause the DB2 instance to crash via a specially crafted SQLJRA packet.
8) A vulnerability in "SYSPROC.NNSTAT" can be exploited to manipulate certain data.
For more information see vulnerability #3 in: SA29022
9) A vulnerability exists related to JAR file administration routines, which can be exploited to cause a DoS.
For more information see vulnerability #4 in: SA29022
