Hackers can influence voters with media and breach campaigns, or try tampering with votes. Or they can combine these tactics to even greater effect.

A flaw was discovered in the RESTEasy Reactive implementation in Quarkus. Due to security checks for some JAX-RS endpoints being performed after serialization, more processing resources are consumed while the HTTP request is checked. In certain configurations, if an attacker has knowledge of any POST, PUT, or PATCH request paths, they can potentially identify vulnerable endpoints and trigger excessive resource usage as the endpoints process the requests. This can result in a denial of service.

Attacks by a previously unknown threat actor leveraged two bugs in firewall devices to install custom backdoors on several government networks globally.

Ubuntu Security Notice 6750-1 - Multiple security issues were discovered in Thunderbird. If a user were tricked into opening a specially crafted website in a browsing context, an attacker could potentially exploit these to cause a denial of service, obtain sensitive information, bypass security restrictions, cross-site tracing, or execute arbitrary code. Bartek Nowotarski discovered that Thunderbird did not properly limit HTTP/2 CONTINUATION frames. An attacker could potentially exploit this issue to cause a denial of service.

Ubuntu Security Notice 6657-2 - USN-6657-1 fixed several vulnerabilities in Dnsmasq. This update provides the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Elias Heftrig, Haya Schulmann, Niklas Vogel, and Michael Waidner discovered that Dnsmasq incorrectly handled validating DNSSEC messages. A remote attacker could possibly use this issue to cause Dnsmasq to consume resources, leading to a denial of service. It was discovered that Dnsmasq incorrectly handled preparing an NSEC3 closest encloser proof. A remote attacker could possibly use this issue to cause Dnsmasq to consume resources, leading to a denial of service. It was discovered that Dnsmasq incorrectly set the maximum EDNS.0 UDP packet size as required by DNS Flag Day 2020. This issue only affected Ubuntu 23.10.

Ubuntu Security Notice 6749-1 - It was discovered that FreeRDP incorrectly handled certain context resets. If a user were tricked into connecting to a malicious server, a remote attacker could use this issue to cause FreeRDP to crash, resulting in a denial of service, or possibly execute arbitrary code. Evgeny Legerov discovered that FreeRDP incorrectly handled certain memory operations. If a user were tricked into connecting to a malicious server, a remote attacker could use this issue to cause FreeRDP to crash, resulting in a denial of service, or possibly execute arbitrary code.

Red Hat Security Advisory 2024-2060-03 - Red Hat OpenShift Virtualization release 4.14.5 is now available with updates to packages and images that fix several bugs and add enhancements. Issues addressed include a denial of service vulnerability.

Within BEC attacks, adversaries will send phishing emails appearing to be from a known or reputable source making a valid request, such as updating payroll direct deposit information.
