10 verified briefings on Dos. Each story includes a plain-English summary, why it matters, and the concrete action engineering teams should take.
A vulnerability was discovered in Ubuntu's System Security Services Daemon (SSSD). A local attacker can exploit this by sending malformed data to the PAM passkey responder, causing it to crash. This results in a denial of service, preventing users from authenticating on affected systems.
A security vulnerability has been discovered in GStreamer Good Plugins. Specially crafted MP4 audio files can cause applications using the framework to crash, leading to a denial-of-service condition. This affects systems relying on GStreamer for multimedia processing. Users should apply available security updates.
Ubuntu has released a security update for its 18.04 LTS and 20.04 LTS versions. The patch addresses a denial-of-service vulnerability in the OpenCC library, which could be triggered by an attacker using specially crafted, truncated UTF-8 input to crash applications using the library.
A denial-of-service vulnerability was found in the Qt Declarative module. Attackers can exploit improperly validated image attributes in Qt Quick's Text component to trigger excessive resource consumption, causing applications to crash. This affects developers using the cross-platform framework and requires patching.
A denial-of-service vulnerability was found in pip, the Python package manager. The flaw, related to how its urllib3 library handles compressed data, could allow an attacker to crash development environments and CI/CD pipelines by consuming excessive resources. Ubuntu has released a patch to fix the issue.
A vulnerability in .NET allows attackers to trigger an infinite loop by sending a specially crafted network request. This can exhaust system resources, leading to a denial of service (DoS) and potential service outages for applications built on the framework, requiring an immediate patch.
Ubuntu has released a security update for a high-impact denial-of-service (DoS) vulnerability in Protocol Buffers. The flaw affects the Python library on Ubuntu 18.04 and 20.04 LTS, allowing attackers to crash applications and disrupt services by consuming excessive resources.
A vulnerability has been found in Dnsmasq, a common network service for DNS and DHCP. When configured with a specific option, mishandled BOOTREPLY packets can allow a remote attacker to crash the service, causing a denial of service, or potentially execute arbitrary code on the system.
A high-severity Denial of Service (DoS) vulnerability has been discovered in the 'multipart' library, a common tool for handling web file uploads. Attackers can send specially crafted HTTP headers to trigger excessive resource consumption, potentially crashing servers and causing service outages for applications using the library.
A new remote denial-of-service vulnerability, named HTTP/2 Bomb, affects major web servers including NGINX, Apache, Microsoft IIS, Envoy, and Cloudflare. The flaw exists in the default HTTP/2 configuration of these servers, making them susceptible to attack without any special setup, according to researchers.
