Oracle : Security Vulnerabilities, CVEs, (Denial of service)

Denial of service in Oracle TNSLSNR SQL*Net Listener via a malformed string to the listener port, aka NERP.

Oracle Webserver 2.1, when serving PL/SQL stored procedures, allows remote attackers to cause a denial of service via a long HTTP GET request.

Oracle Web Listener for AIX versions 4.0.7.0.0 and 4.0.8.1.0 allows remote attackers to cause a denial of service via a malformed URL.

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.

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.

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 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 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 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.

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

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.

Oracle9iAS Web Cache 2.0.0.x allows remote attackers to cause a denial of service via (1) a request to TCP ports 1100, 4000, 4001, and 4002 with a large number of null characters, and (2) a request to TCP port 4000 with a large number of "." characters.

The administration module for Oracle Web Cache in Oracle9iAS (9i Application Suite) 9.0.2 allows remote attackers to cause a denial of service (crash) via (1) an HTTP GET request containing a ".." (dot dot) sequence, or (2) a malformed HTTP GET request with a chunked Transfer-Encoding with missing data.

Transparent Network Substrate (TNS) Listener in Oracle 9i 9.0.1.1 allows remote attackers to cause a denial of service (CPU consumption) via a single malformed TCP packet to port 1521.

Buffer overflows in PL/SQL module 3.0.9.8.2 in Oracle 9i Application Server 1.0.2.x allow remote attackers to cause a denial of service or execute arbitrary code via (1) a long help page request without a dadname, which overflows the resulting HTTP Location header, (2) a long HTTP request to the plsql module, (3) a long password in the HTTP Authorization, (4) a long Access Descriptor (DAD) password in the addadd form, or (5) a long cache directory name.

PL/SQL module 3.0.9.8.2 in Oracle 9i Application Server 1.0.2.x allows remote attackers to cause a denial of service (crash) via an HTTP Authorization header without an authentication type.

OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, does not properly handle ASCII representations of integers on 64 bit platforms, which could allow attackers to cause a denial of service and possibly execute arbitrary code.

The ASN1 library in OpenSSL 0.9.6d and earlier, and 0.9.7-beta2 and earlier, allows remote attackers to cause a denial of service via invalid encodings.

Buffer overflows in the ApacheBench benchmark support program (ab.c) in Apache before 1.3.27, and Apache 2.x before 2.0.43, allow a malicious web server to cause a denial of service and possibly execute arbitrary code via a long response.

SQL*NET listener for Oracle Net Oracle9i 9.0.x and 9.2 allows remote attackers to cause a denial of service (crash) via certain debug requests that are not properly handled by the debugging feature.

TNS Listener in Oracle Net Services for Oracle 9i 9.2.x and 9.0.x, and Oracle 8i 8.1.x, allows remote attackers to cause a denial of service (hang or crash) via a SERVICE_CURLOAD command.

Signed integer vulnerability in the COM_TABLE_DUMP package for MySQL 3.23.x before 3.23.54 allows remote attackers to cause a denial of service (crash or hang) in mysqld by causing large negative integers to be provided to a memcpy call.

libmysqlclient client library in MySQL 3.x to 3.23.54, and 4.x to 4.0.6, does not properly verify length fields for certain responses in the (1) read_rows or (2) read_one_row routines, which allows remote attackers to cause a denial of service and possibly execute arbitrary code.

Double-free vulnerability in mysqld for MySQL before 3.23.55 allows attackers with MySQL access to cause a denial of service (crash) via mysql_change_user.

Multiple buffer overflows in the XML Database (XDB) functionality for Oracle 9i Database Release 2 allow local users to cause a denial of service or hijack user sessions.
