The remote Debian host is missing a security-related update.
Several vulnerabilities were discovered in the lighttpd web server. - CVE-2014-2323 Jann Horn discovered that specially crafted host names can be used to inject arbitrary MySQL queries in lighttpd servers using the MySQL virtual hosting module (mod_mysql_vhost). This only affects installations with the lighttpd-mod-mysql-vhost binary package installed and in use. - CVE-2014-2324 Jann Horn discovered that specially crafted host names can be used to traverse outside of the document root under certain situations in lighttpd servers using either the mod_mysql_vhost, mod_evhost, or mod_simple_vhost virtual hosting modules. Servers not using these modules are not affected.
Upgrade the lighttpd packages. For the oldstable distribution (squeeze), these problems have been fixed in version 1.4.28-2+squeeze1.6. For the stable distribution (wheezy), these problems have been fixed in version 1.4.31-4+deb7u3.
