CVE-2024-29903 is a vulnerability found in Cosign, a code signing and transparency tool for containers and binaries. The vulnerability exists in versions prior to 2.2.4 and can be exploited by maliciously-crafted software artifacts to cause a denial of service on the host machine running Cosign, impacting all services on the machine.
