HTTP Request Smuggling

bottle is vulnerable to HTTP request smuggling. An attacker is able to send a malicious request containing a separate query parameter using a semicolon ;, resulting in unexpected interpretations of the request between the proxy and the server, and potentially poisoning the web cache...

CVE-2020-25685

A flaw was found in dnsmasq before version 2.83. When getting a reply from a forwarded query, dnsmasq checks in forward.c:replyquery, which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash CRC32 when dnsmasq is compiled without DNSSE...
