Three vulnerabilities have been discovered in the mt-daapd DAAP audio server (also known as the Firefly Media Server). The Common Vulnerabilities and Exposures project identifies the following three problems:
Insufficient validation and bounds checking of the Authorization: HTTP header enables a heap buffer overflow, potentially enabling the execution of arbitrary code.
Format string vulnerabilities in debug logging within the authentication of XML-RPC requests could enable the execution of arbitrary code.
An integer overflow weakness in the handling of HTTP POST variables could allow a heap buffer overflow and potentially arbitrary code execution.
