Vulnerable Configurations
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 Debian Local Security Checks NASL id DEBIAN_DLA-484.NASL description Several security vulnerabilities were discovered in graphicsmagick a tool to manipulate image files. GraphicsMagick is a fork of ImageMagick and also affected by vulnerabilities collectively known as ImageTragick, that are the consequence of lack of sanitization of untrusted input. An attacker with control on the image input could, with the privileges of the user running the application, execute code (CVE-2016-3714), make HTTP GET or FTP requests (CVE-2016-3718), or delete (CVE-2016-3715), move (CVE-2016-3716), or read (CVE-2016-3717) local files. To address these concerns the following changes have been made : 1. Remove automatic detection/execution of MVG based on file header or file extension. 2. Remove the ability to cause an input file to be deleted based on a filename specification. 3. Improve the safety of delegates.mgk by removing gnuplot support, removing manual page support, and by adding -dSAFER to all ghostscript invocations. 4. Sanity check the MVG image primitive filename argument to assure that last seen 2020-03-17 modified 2016-05-24 plugin id 91299 published 2016-05-24 reporter This script is Copyright (C) 2016-2020 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/91299 title Debian DLA-484-1 : graphicsmagick security update (ImageTragick) NASL family Amazon Linux Local Security Checks NASL id ALA_ALAS-2016-678.NASL description An out-of-bounds read flaw was found in the parsing of GIF files using GraphicsMagick. last seen 2020-06-01 modified 2020-06-02 plugin id 90271 published 2016-04-01 reporter This script is Copyright (C) 2016-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/90271 title Amazon Linux AMI : GraphicsMagick (ALAS-2016-678) NASL family Fedora Local Security Checks NASL id FEDORA_2016-49BF88CD29.NASL description Security fix for CVE-2015-8808 Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory.
