PARTIAL Summary
Stack-based buffer overflow in kkstrtext.h in ktools library 0.3 and earlier, as used in products such as (1) centericq, (2) orpheus, (3) motor, and (4) groan, allows local users or remote attackers to execute arbitrary code via a long parameter to the VGETSTRING macro.

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.

Impact : A remote attacker could entice a user to use a malicious file or input, which could lead to the crash of Motor and possibly the execution of arbitrary code. Workaround : There is no known workaround at this time. last seen 2020-06-01 modified 2020-06-02 plugin id 22289 published 2006-08-30 reporter This script is Copyright (C) 2006-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/22289 title GLSA-200608-27 : Motor: Execution of arbitrary code NASL family Gentoo Local Security Checks NASL id GENTOO_GLSA-200512-11.NASL description The remote host is affected by the vulnerability described in GLSA-200512-11 (CenterICQ: Multiple vulnerabilities) Gentoo developer Wernfried Haas discovered that when the last seen 2020-06-01 modified 2020-06-02 plugin id 20352 published 2005-12-30 reporter This script is Copyright (C) 2005-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/20352 title GLSA-200512-11 : CenterICQ: Multiple vulnerabilities NASL family Debian Local Security Checks NASL id DEBIAN_DSA-1083.NASL description Mehdi Oudad and Kevin Fernandez discovered a buffer overflow in the ktools library which is used in motor, an integrated development environment for C, C++ and Java, which may lead local attackers to execute arbitrary code. last seen 2020-06-01 modified 2020-06-02 plugin id 22625 published 2006-10-14 reporter This script is Copyright (C) 2006-2019 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/22625 title Debian DSA-1083-1 : motor - buffer overflow
