FreeBSD -- Remote code execution via malicious DHCP options
Problem Description: The BOOTP file field is written to the lease file without escaping embedded double-quotes, allowing injection of arbitrary dhclient.conf directives. When the lease file is subsequently re-parsed by dhclient, e.g., after a system restart, an attacker-controlled field from the...
CVE-2025-34305
IPFire versions prior to 2.29 Core Update 198 contain multiple stored cross-site scripting XSS vulnerabilities caused by a bug in the cleanhtml function /var/ipfire/header.pl that fails to apply HTML-entity encoding to user input. When an authenticated user submits data to affected endpoints - fo...
CVE-2025-12198
A heap-based buffer overflow vulnerability in dnsmasq within the parsehex function of src/util.c. When parsing malformed DHCP option values in configuration files, dnsmasq miscalculates the output length and writes beyond the allocated heap buffer. This can cause a crash Denial of Service and, in...

Linux Distros Unpatched Vulnerability : CVE-2021-40085
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An issue was discovered in OpenStack Neutron before 16.4.1, 17.x before 17.2.1, and 18.x before 18.1.1. Authenticated attackers can reconfigure dnsmasq via a...
CVE-2011-1930
In klibc 1.5.20 and 1.5.21, the DHCP options written by ipconfig to /tmp/net-$DEVICE.conf are not properly escaped. This may allow a remote attacker to send a specially crafted DHCP reply which could execute arbitrary code with the privileges of any process which sources DHCP options...
The vulnerability of TP-Link Omada ER605 VPN router’s microprogramming system lies in the ability to write code outside the buffer, allowing a hacker to execute arbitrary code in the context of the root user.
The vulnerability of TP-Link Omada ER605 VPN router’s microprogramming software is related to the writing beyond buffer boundaries. Exploiting this vulnerability allows a malicious actor to execute arbitrary code in the context of the root user, as a result of processing DHCP options...

Name of the Vulnerable Software and Affected Versions: TP-Link Omada ER605 affected versions not specified Description: This issue allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link Omada ER605 routers. The specific flaw exists within the handling of...
SUSE CVE-2018-5732
Failure to properly bounds-check a buffer used for processing DHCP options allows a malicious server or an entity masquerading as a server to cause a buffer overflow and resulting crash in dhclient by sending a response containing a specially constructed options section. Affects ISC DHCP versions...
