TITLE: DB2 Universal Database Multiple Vulnerabilities SECUNIA ADVISORY ID: SA12733 VERIFY ADVISORY: http://secunia.com/advisories/12733/ CRITICAL: Moderately critical IMPACT: Unknown, Security Bypass, DoS, System access WHERE: >From local network SOFTWARE: DB2 Universal Database 7.x http://secunia.com/product/858/ DB2 Universal Database 8.x http://secunia.com/product/857/ DESCRIPTION: Multiple vulnerabilities have been reported in DB2 Universal Database, where some of the vulnerabilities can be exploited to compromise a vulnerable system. 1) Improper permissions for the "everyone" group on Windows systems makes it possible to access certain DB2 resources, which should not be possible. 2) An input validation error within the DB2 security service can be exploited to crash it by sending specially crafted data. 3) An access control error makes it possible for users to signal the DB2 UDB instance to shut down. 4) Unspecified boundary errors exist, which can be exploited to cause buffer overflows and may allow execution of arbitrary code. 5) A boundary error within the handling of library names can be exploited to cause a stack-based buffer overflow by passing an overly long library name. Successful exploitation allows execution of arbitrary code. 6) An unspecified vulnerability exists within the satellite user-defined function SATADMIN.SATENCRYPT. 7) An unspecified vulnerability exists within the JDBC listener. 8) An unspecified vulnerability exists within the conversion of DTS to strings. 9) A boundary error within the handling of the "DB2LPORT" environment variable can be exploited to cause a buffer overflow by setting it to an overly long value. 10) A boundary error within the DB2FMP process can be exploited to cause a buffer overflow by passing an overly long command string. 11) Boundary errors within some XML extender UDFS can be exploited to cause stack-based buffer overflows by passing overly long parameters. SOLUTION: Apply DB2 FixPak 6a or 7a. http://www-306.ibm.com/software/data/db2/udb/support/downloadv8.html Fixes for DB2 7.2 will be included in FixPak 13, which will be released early October. http://www-306.ibm.com/software/data/db2/udb/support/downloadv7.html PROVIDED AND/OR DISCOVERED BY: Some of the vulnerabilities have been reported by NGSSoftware.
