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.

NASL family FreeBSD Local Security Checks NASL id FREEBSD_PKG_43A1B8F934514F3CB4FC730C0F5876C1.NASL description sam2p developers report : In sam2p 0.49.3, a heap-based buffer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp. In sam2p 0.49.3, the in_xpm_reader function in in_xpm.cpp has an integer signedness error, leading to a crash when writing to an out-of-bounds array element. In sam2p 0.49.3, an integer overflow exists in the pcxLoadImage24 function of the file in_pcx.cpp, leading to an invalid write operation. In sam2p 0.49.3, the pcxLoadRaster function in in_pcx.cpp has an integer signedness error leading to a heap-based buffer overflow. Because of an integer overflow in sam2p 0.49.3, a loop executes 0xffffffff times, ending with an invalid read of size 1 in the Image::Indexed::sortPal function in image.cpp. However, this also causes memory corruption because of an attempted write to the invalid d[0xfffffffe] array element. In sam2p 0.49.3, there is an invalid read of size 2 in the parse_rgb function in in_xpm.cpp. However, this can also cause a write to an illegal address. last seen 2020-06-01 modified 2020-06-02 plugin id 103557 published 2017-09-29 reporter This script is Copyright (C) 2017-2018 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/103557 title FreeBSD : sam2p -- multiple issues (43a1b8f9-3451-4f3c-b4fc-730c0f5876c1) code # # (C) Tenable Network Security, Inc. # # The descriptive text and package checks in this plugin were # extracted from the FreeBSD VuXML database : # # Copyright 2003-2018 Jacques Vidrine and contributors # # Redistribution and use in source (VuXML) and 'compiled' forms (SGML, # HTML, PDF, PostScript, RTF and so forth) with or without modification, # are permitted provided that the following conditions are met: # 1.
