Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
- Client-side Injection-induced Buffer Overflow This type of attack exploits a buffer overflow vulnerability in targeted client software through injection of malicious content from a custom-built hostile service.
- Filter Failure through Buffer Overflow In this attack, the idea is to cause an active filter to fail by causing an oversized transaction. An attacker may try to feed overly long input strings to the program in an attempt to overwhelm the filter (by causing a buffer overflow) and hoping that the filter does not fail securely (i.e. the user input is let into the system unfiltered).
- MIME Conversion An attacker exploits a weakness in the MIME conversion routine to cause a buffer overflow and gain control over the mail server machine. The MIME system is designed to allow various different information formats to be interpreted and sent via e-mail. Attack points exist when data are converted to MIME compatible format and back.

It is, therefore, affected by one or more of the following issues : - The Install component on Linux, UNIX, and Windows enforces an unintended limit on password length, which makes it easier for attackers to obtain access via a brute-force attack. (IC62856) - The Security component logs AUDIT events by using a USERID and an AUTHID value corresponding to the instance owner, instead of a USERID and an AUTHID value corresponding to the logged-in user account, which makes it easier for remote, authenticated users to execute Audit administration commands without discovery. (IC65184) - A privilege escalation vulnerability exists in the DB2STST program (on Linux and Unix platforms only). (IC65703) - A malicious user could use the DB2DART program to overwrite files owned by the instance owner. (IC65756) - The scalar function REPEAT contains a buffer overflow that a malicious user with a valid database connection could manipulate, causing the DB2 server to trap. (IC65933) - The Net Search Extender implementation in the Text Search component does not properly handle an alphanumeric Fuzzy search, which could allow a remote, authenticated user to consume memory or even hang the system via the last seen 2020-06-01 modified 2020-06-02 plugin id 49120 published 2010-09-07 reporter This script is Copyright (C) 2010-2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/49120 title IBM DB2 9.5 < Fix Pack 6a Multiple Vulnerabilities
