Title: Varnish: Multiple vulnerabilities (GLSA 201607-10)
Date: July 20, 2016
Improper input validation in Varnish allows remote attackers to
conduct HTTP smuggling attacks, and possibly trigger a buffer overflow.
Varnish is a web application accelerator.
Vulnerable: < 3.0.7
Unaffected: >= 3.0.7
Architectures: All supported architectures
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.
All Varnish users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=www-servers/varnish-3.0.7"
