Title: Oracle /tmp Race Condition Vulnerability
Severity: MODERATE
Description:
The Oracle binary for Unix systems, 'oracle', is believed to contain a race condition vulnerability.
Oracle writes a temporary file to a user-definable directory location based on the value of an environment variable. When certain temporary files are created, their filenames are based on the process ID of the 'oracle' utility.
Attackers can anticipate the process ID of 'oracle' and create symbolic links with guessed filenames in an attacker-defined directory pointing to files writeable by oracle.
If the filename of the symbolic link was correctly guessed, the file pointed to will be overwritten. This will occur with user 'oracle' privileges because the 'oracle' binary is installed setuid.
This vulnerability can be used to cause a denial of service (ie, corrupting db data files).

- Oracle Oracle8i Standard Edition 8.0.6
- Oracle Oracle8i Standard Edition 8.1.0 x
