Summary
A local root privilege escalation vulnerability was found in Exim, Debian's default mail transfer agent, in configurations using the perl_startup option (Only Exim via exim4-daemon-heavy enables Perl support). To address the vulnerability, updated Exim versions clean the complete execution environment by default, affecting Exim and subprocesses such as transports calling other programs, and thus may break existing installations. New configuration options (keep_environment, add_environment) were introduced to adjust this behavior.
