Oracle : Security Vulnerabilities, CVEs, Published In 2001 (Denial of service)

Oracle Internet Directory Server 2.1.1.x and 3.0.1 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via invalid encodings of BER OBJECT-IDENTIFIER values, as demonstrated by the PROTOS LDAPv3 test suite.

Buffer overflow in MySQL before 3.23.31 allows attackers to cause a denial of service and possibly gain privileges.

Oracle listener before Oracle 9i allows attackers to cause a denial of service by repeatedly sending the first portion of a fragmented Oracle command without sending the remainder of the command, which causes the listener to hang.

Oracle listener in Oracle 8i on Solaris allows remote attackers to cause a denial of service via a malformed connection packet with a maximum transport data size that is set to 0.

Oracle listener between Oracle 9i and Oracle 8.0 allows remote attackers to cause a denial of service via a malformed connection packet that contains an incorrect requester_version value that does not match an expected offset to the data.

Oracle Listener in Oracle 7.3 and 8i allows remote attackers to cause a denial of service via a malformed connection packet with a large offset_to_data value.

Oracle listener process on Windows NT redirects connection requests to another port and creates a separate thread to process the request, which allows remote attackers to cause a denial of service by repeatedly connecting to the Oracle listener but not connecting to the redirected port.

Transparent Network Substrate (TNS) over Net8 (SQLNet) in Oracle 8i 8.1.7 and earlier allows remote attackers to cause a denial of service via a malformed SQLNet connection request with a large offset in the header extension.
