PARTIAL Summary
Stack-based buffer overflow in the parsePresentationContext function in storescp in DICOM dcmtk-3.6.0 and earlier allows remote attackers to cause a denial of service (segmentation fault) via a long string sent to TCP port 4242.

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-755.NASL description At several places in the code a wrong length of ACSE data structures received over the network can cause overflows or underflows when processing those data structures. Related checks have been added at various places in order to prevent such (possible) attacks. Thanks to Kevin Basista for the report. The bug will indeed affect all DCMTK-based server applications that accept incoming DICOM network connections that are using the dcmtk-3.6.0 and earlier versions.

This could lead to denial-of-service (via application crash) or arbitrary code execution. last seen 2020-06-01 modified 2020-06-02 plugin id 96193 published 2017-01-03 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/96193 title Debian DSA-3749-1 : dcmtk - security update
