Oracle Database Server TZ_OFFSET() buffer overflow
| oracle-tzoffset-bo (11326) |  High Risk |
Description:
Oracle Database Servers are vulnerable to a buffer overflow in the TZ_OFFSET function, caused by improper bounds checking of user-supplied input. By supplying an overly long argument to the TZ_OFFSET function, a remote attacker could overflow a buffer and execute arbitrary commands on the server with elevated privileges.
Platforms Affected:
- Oracle, Database Server 8.0.6
- Oracle, Database Server 8.1.7
- Oracle, Database Server 8.1.7.1
- Oracle, Database Server 9.0
- Oracle, Database Server 9.0.1 R1
- Oracle, Database Server 9.0.1.2 R1
- Oracle, Database Server 9.0.1.3 R1
- Oracle, Database Server 9.0.2
- Oracle, Database Server 9.2.1 R2
- Oracle, Database Server 9.2.2 R2
- Oracle, Database Server R2
Remedy:
Apply the appropriate patch for your system, as listed in Oracle Security Alert #49. See References.
Consequences:
Gain Access
