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: CVE-2007-5824 Insufficient validation and bounds checking of the Authorization: HTTP header enables a heap buffer overflow, potentially enabling the execution of arbitrary code. CVE-2007-5825 Format string vulnerabilities in debug logging within the authentication of XML-RPC requests could enable the execution of arbitrary code. CVE-2008-1771 An integer overflow weakness in the handling of HTTP POST variables could allow a heap buffer overflow and potentially arbitrary code execution. For the stable distribution (etch), these problems have been fixed in version 0.2.4+r1376-1.1+etch1. For the unstable distribution (sid), these problems have been fixed in version 0.9~r1696-1.3. We recommend that you upgrade your mt-daapd package.
