HTTP Request Smuggling in Undertow
A flaw was discovered in all versions of Undertow before Undertow 2.2.0.Final, where HTTP request smuggling related to CVE-2017-2666 is possible against HTTP/1.x and HTTP/2 due to permitting invalid characters in an HTTP request. This flaw allows an attacker to poison a web-cache, perform an XSS attack, or obtain sensitive information from request other than their own.

Logic error in Legion of the Bouncy Castle BC Java
An issue was discovered in Legion of the Bouncy Castle BC Java 1.65 and 1.66. The OpenBSDBCrypt.checkPassword utility method compared incorrect data when checking the password, allowing incorrect passwords to indicate they were matching with previously hashed ones that were different.

Information Disclosure in Guava
A temp directory creation vulnerability exists in Guava prior to version 32.0.0 allowing an attacker with access to the machine to potentially access data in a temporary directory created by the Guava `com.google.common.io.Files.createTempDir()`. The permissions granted to the directory created default to the standard unix-like /tmp ones, leaving the files open. Maintainers recommend explicitly changing the permissions after the creation of the directory, or removing uses of the vulnerable method.
