IBM DB2 buildDasPaths() DASPROF environment variable buffer overflow
| db2-environment-variables-bo (36067) |  High Risk |
Description:
IBM DB2 is vulnerable to a stack-based buffer overflow in the buildDasPaths() function. By setting an overly long DASPROF environment variable, a local attacker could overflow a buffer and execute arbitrary code on the system with root privileges.
