Summary

Unspecified vulnerability in the Network Authentication component in Oracle Database 10.1.0.5 and 10.2.0.4 allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors. NOTE: the previous information was obtained from the October 2009 CPU. Oracle has not commented on claims from an independent researcher that this is related to improper validation of the AUTH_SESSKEY parameter length that leads to arbitrary code execution.

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
