Vulnerabilities > CVE-2017-6458 - Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Attack vector
NETWORK Attack complexity
LOW Privileges required
LOW Confidentiality impact
HIGH Integrity impact
HIGH Availability impact
HIGH Summary
Multiple buffer overflows in the ctl_put* functions in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allow remote authenticated users to have unspecified impact via a long variable.
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 Misc. NASL id NTP_4_2_8P10.NASL description The version of the remote NTP server is 4.x prior to 4.2.8p10. It is, therefore, affected by the following vulnerabilities : - A denial of service vulnerability exists in the receive() function within file ntpd/ntp_proto.c due to the expected origin timestamp being cleared when a packet with a zero origin timestamp is received. An unauthenticated, remote attacker can exploit this issue, via specially crafted network packets, to reset the expected origin timestamp for a target peer, resulting in legitimate replies being dropped. (CVE-2016-9042) - An out-of-bounds write error exists in the mx4200_send() function within file ntpd/refclock_mx4200.c due to improper handling of the return value of the snprintf() and vsnprintf() functions. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or possibly the execution of arbitrary code. However, neither the researcher nor vendor could find any exploitable code path. (CVE-2017-6451) - A stack-based buffer overflow condition exists in the addSourceToRegistry() function within file ports/winnt/instsrv/instsrv.c due to improper validation of certain input when adding registry keys. A local attacker can exploit this to execute arbitrary code. (CVE-2017-6452) - A flaw exists due to dynamic link library (DLL) files being preloaded when they are defined in the inherited environment variable last seen 2020-06-01 modified 2020-06-02 plugin id 97988 published 2017-03-27 reporter This script is Copyright (C) 2017-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/97988 title Network Time Protocol Daemon (ntpd) 4.x < 4.2.8p10 Multiple Vulnerabilities NASL family PhotonOS Local Security Checks NASL id PHOTONOS_PHSA-2017-0010.NASL description An update of [binutils,ntp,libarchive] packages for PhotonOS has been released. last seen 2019-02-21 modified 2019-02-07 plugin id 111859 published 2018-08-17 reporter Tenable source https://www.tenable.com/plugins/index.php?view=single&id=111859 title Photon OS 1.0: Binutils / Libarchive / Ntp PHSA-2017-0010 (deprecated) NASL family MacOS X Local Security Checks NASL id MACOS_10_13.NASL description The remote host is running a version of Mac OS X that is prior to 10.10.5, 10.11.x prior to 10.11.6, 10.12.x prior to 10.12.6, or is not macOS 10.13.
