IBM DB2 directory creation format string
| db2-message-file-format-string (36106) |  High Risk |
Description:
IBM DB2 could allow a remote attacker to execute arbitrary code on the system, caused by format string vulnerability that exists when creating directories. By sending a localized message file containing specially-crafted format specifiers using the OSSEMEMDBG or TRC_LOG_FILE environment variable in db2licd, a local attacker could exploit this vulnerability to execute arbitrary code on the system with root privileges.
