Security readout for executives and security teams

This is an old Sendmail issue affecting Red Hat Enterprise Linux 4 Update 4 and earlier. External email could be accepted using the localhost.localdomain domain, which may let attackers make messages look more trusted than they are. Exposure is most likely limited to legacy RHEL 4 systems running the affected Sendmail package and accepting mail from external hosts. Modern supported systems are not identified in the source bundle. Treat this as a legacy exposure cleanup item unless affected internet-facing mail servers still exist. Business risk is email trust abuse, not confirmed system takeover from the provided evidence. Mitigation focus: Check RHSA-2007:0252 and relevant vendor advisories for fixed packages.; Inventory legacy RHEL 4 mail hosts running Sendmail 8.13.1-2 or earlier.; Apply vendor-provided updates where available and applicable..
