An unsafe data binding used to populate an object from request parameters (either query parameters or form data) to set a Tomcat specific ClassLoader in Spring MVC and Spring WebFlux applications allows unauthenticated attackers to upload and execute a JSP file in the Tomcat virtual file system webapps directory.
A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as commands. An attacker can leverage this by crafting environment variables in such a way it'll induce pkexec to execute arbitrary code. When successfully executed the attack can cause a local privilege escalation giving unprivileged users administrative rights on the target machine.
