Title:	Debian: Security Advisory (DSA-3517-1)
Summary:	The remote host is missing an update for the Debian 'exim4' package(s) announced via the DSA-3517-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'exim4' package(s) announced via the DSA-3517-1 advisory. Vulnerability Insight: 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. More information can be found in the upstream advisory at [link moved to references] 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. Affected Software/OS: 'exim4' package(s) on Debian 7, Debian 8. Solution: Please install the updated package(s). CVSS Score: 6.9 CVSS Vector: AV:L/AC:M/Au:N/C:C/I:C/A:C
