Background ========== Multi-Threaded DAAP Daemon (mt-daapd), also known as the Firefly Media Server, is a software to serve digital music to the Roku Soundbridge and Apple's iTunes. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 media-sound/mt-daapd < 0.2.4.1 >= 0.2.4.1 Description =========== nnp discovered multiple vulnerabilities in the XML-RPC handler in the file webserver.c. The ws_addarg() function contains a format string vulnerability, as it does not properly sanitize username and password data from the "Authorization: Basic" HTTP header line (CVE-2007-5825). The ws_decodepassword() and ws_getheaders() functions do not correctly handle empty Authorization header lines, or header lines without a ':' character, leading to NULL pointer dereferences (CVE-2007-5824). Impact ====== A remote attacker could send specially crafted HTTP requests to the web server in the Multi-Threaded DAAP Daemon, possibly leading to the execution of arbitrary code with the privileges of the user running the web server or a Denial of Service. Workaround ========== There is no known workaround at this time. Resolution ========== All Multi-Threaded DAAP Daemon users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=media-sound/mt-daapd-0.2.4.1" References ========== [ 1 ] CVE-2007-5824 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5824 [ 2 ] CVE-2007-5825 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-5825 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200712-18.xml Concerns? ========= Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us.
