The GIOP service in TNS Listener in the Oracle Net Services component in Oracle Database 9.0.1.5+, 9.2.0.8, 9.2.0.8DV, 10.1.0.5, and 10.2.0.3 allows remote attackers to cause a denial of service (crash) or read potentially sensitive memory via a connect GIOP packet with an invalid data size, which triggers a buffer over-read, aka DB22.
