libssh: libssh: Denial of Service via inefficient regular expression processing

A flaw was found in libssh. A remote attacker, by controlling client configuration files or knownhosts files, could craft specific hostnames that when processed by the matchpattern function can lead to inefficient regular expression backtracking. This can cause timeouts and resource exhaustion,...

curl: Connection reuse ignores haproxyprotocol and HAPROXY_CLIENT_IP settings, allowing PROXY context to persist across transfers

Summary: libcurl's connection pool match logic does not include the CURLOPTHAPROXYPROTOCOL setting or the CURLOPTHAPROXYCLIENTIP value in its connection match key. Two transfers issued through the same Curleasy or via a shared connection cache CURLLOCKDATACONNECT therefore share one TCP connectio...
