A flaw was discovered in FasterXML jackson-databind in versions prior to 2.9.9. The vulnerability would permit polymorphic deserialization of malicious objects using the logback-core gadget when used in conjunction with polymorphic type handling methods such as enableDefaultTyping() or when @JsonTypeInfo is using Id.CLASS or Id.MINIMALCLASS or in any other way which ObjectMapper.readValue might instantiate objects from unsafe sources. Depending on the classpath content, remote code execution may be possible.
In Apache HTTP Server 2.4.17 to 2.4.34, by sending continuous, large SETTINGS frames a client can occupy a connection, server thread and CPU time without any connection timeout coming to effect. This affects only HTTP/2 connections. A possible mitigation is to not enable the h2 protocol.
A flaw was found in Mozilla Thunderbird before version 52.9. Decrypted S/MIME parts hidden with CSS or <plaintext> can leak plaintext when included in a HTML reply/forward.

A specially crafted request could have crashed the Apache HTTP Server prior to version 2.4.30, due to an out of bound access after a size limit is reached by reading the HTTP header. This vulnerability is considered very hard if not impossible to trigger in non-debug mode (both log and build level), so it is classified as low risk for common server usage.
Versions Affected: httpd 2.0.1 to 2.4.29

Apache HTTP Server (httpd) through version 2.4.29 has a vulnerability in the handling of HTTP session headers in modsession. When modsession is configured to forward its session data to CGI applications (SessionEnv on, not the default), a remote user may influence their content by using a "Session" header.
