{"vuid":"VU#840666","idnumber":"840666","name":"Oracle9i Database contains remotely exploitable buffer overflow in \"TO_TIMESTAMP_TZ\" function","keywords":["oracle","buffer overflow","oracle9i","TO_TIMESTAMP_TZ"],"overview":"A remotely exploitable buffer overflow vulnerability exists in Oracle9i Database.","clean_desc":"A buffer overflow vulnerability exists on all platforms in the following versions of Oracle9i Database: Oracle9i Database Release 2\n9i Release 1\n8i\n8.1.7\n8.0.6\nA buffer overflow exists in TO_TIMESTAMP_TZ (a function responsible for handling timezone-related calculations). By supplying an overly long character string to the function, a remote attacker can overwrite a return address on the Oracle process stack, resulting in the ability to execute arbitrary code with the privileges of the vulnerable process. This process typically runs as \"Oracle\" on Linux and UNIX hosts and as \"Local System\" on Windows systems. Oracle has published Oracle Security Alert #50 regarding this issue. Patches for this vulnerability are available from Metalink (the Oracle Worldwide Support Services web site).","impact":"A remote attacker can overwrite a return address on the Oracle process stack, resulting in the ability to execute arbitrary code with the privileges of the vulnerable process.
