Background ========== Pound is a reverse proxy, load balancer and HTTPS front-end. It allows to distribute the load on several web servers and offers a SSL wrapper for web servers that do not support SSL directly.

Impact ====== An attacker could exploit this vulnerability by sending HTTP requests with specially crafted "Content-Length" and "Transfer-Encoding" headers to bypass certain security restrictions or to poison the web proxy cache. Workaround ========== There is no known workaround at this time. Resolution ========== All Pound users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/pound-2.0.5" References ========== [ 1 ] CVE-2005-3751 http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2005-3751 Availability ============ This GLSA and any updates to it are available for viewing at the Gentoo Security Website: http://security.gentoo.org/glsa/glsa-200606-05.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.
