Name of the Vulnerable Software and Affected Versions sendmail versions prior to 8.14.9

Description The issue exists in the sm close on exec function due to incorrect argument order and missing expected FD CLOEXEC flags. This allows local users to access high-numbered file descriptors using a custom mail-delivery program.

Recommendations For sendmail versions prior to 8.14.9, update to version 8.14.9 or later to resolve the issue. As a temporary workaround, consider restricting access to the sm close on exec function until a patch is available.
