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. More information can be found in the upstream advisory at https://www.exim.org/static/doc/CVE-2016-1531.txt For the oldstable distribution (wheezy), this problem has been fixed in version 4.80-7+deb7u2. For the stable distribution (jessie), this problem has been fixed in version 4.84.2-1. For the testing distribution (stretch), this problem has been fixed in version 4.86.2-1. For the unstable distribution (sid), this problem has been fixed in version 4.86.2-1. We recommend that you upgrade your exim4 packages.
