Background ========= monkeyd is a fast, efficient, small and easy to configure web server for Linux. Affected packages ================ ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 www-servers/monkeyd < 0.9.1 > = 0.9.1 Description ========== Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a double expansion error in monkeyd, resulting in a format string vulnerability. Ciaran McCreesh of Gentoo Linux discovered a Denial of Service vulnerability, a syntax error caused monkeyd to zero out unallocated memory should a zero byte file be requested. Impact ===== The format string vulnerability could allow an attacker to send a specially crafted request to the monkeyd server, resulting in the execution of arbitrary code with the permissions of the user running monkeyd. The DoS vulnerability could allow an attacker to disrupt the operation of the web server, should a zero byte file beaccessible. Workaround ========= There is no known workaround at this time. Resolution ========= All monkeyd users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose "> =www-servers/monkeyd-0.9.1" Availability =========== This GLSA and any updates to it are available for viewing at the Gentoo Security Website: https://security.gentoo.org/glsa/200504-14 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. Any security concerns should be addressed to

Background ========= The Monkey HTTP daemon is a Web server written in C that works under Linux and is based on the HTTP/1.1 protocol. It aims to develop a fast, efficient and small web server. Description ========== A bug in the URI processing of incoming requests allows for a Denial of Service to be launched against the webserver, which may cause the server to crash or behave sporadically. Impact ===== Although there are no public exploits known for bug, users are recommended to upgrade to ensure the security of their infrastructure. Workaround ========= There is no immediate workaround; a software upgrade is required. The vulnerable function in the code has been rewritten. Resolution ========= All users are recommended to upgrade monkeyd to 0.8.2: ~ # emerge sync ~ # emerge -pv "> =net-www/monkeyd-0.8.2" ~ # emerge "> =net-www/monkeyd-0.8.2" 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.
