GLSA-201607-12 : Exim: Arbitrary code execution
Medium Nessus Plugin ID 92482
SynopsisThe remote Gentoo host is missing one or more security-related patches.
DescriptionThe remote host is affected by the vulnerability described in GLSA-201607-12 (Exim: Arbitrary code execution)
Vulnerabilities have been discovered in Exim’s implementation of set-uid root and when using ‘perl_startup’. These vulnerabilities require a user account on the Exim server and a configuration that does lookups against files to which the user has edit access.
A local attacker could possibly execute arbitrary code with the privileges of the process, or escalate privileges.
There is no known workaround at this time.
SolutionAll Exim users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=mail-mta/exim-4.87'
