Common Vulnerabilities and Exposures assigned an identifier CVE-2012-3137 to the following vulnerability:

The authentication protocol in Oracle Database 11g 1 and 2 allows remote attackers to obtain the session key and salt for arbitrary users, which leaks information about the cryptographic hash and makes it easier to conduct brute force password guessing attacks, aka "stealth password cracking vulnerability."
