GLSA-201607-10 : Varnish: Multiple vulnerabilities
Medium Nessus Plugin ID 92480
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201607-10 (Varnish: Multiple vulnerabilities)
Varnish fails to properly validate input from HTTP headers, and does not deny requests with multiple Content-Length headers.
Remote attackers could conduct an HTTP response splitting attack, which may further enable them to conduct Cross-Site Scripting (XSS), Cache Poisoning, Defacement, and Page Hijacking.
There is no known workaround at this time.
SolutionAll Varnish users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=www-servers/varnish-3.0.7'
