Security readout for executives and security teams

A specially crafted email header can trigger a memory corruption flaw in old Pegasus Mail clients. If exploited, it may let a remote attacker run code in the context of the user reading or processing mail. This is mainly a legacy endpoint risk. Exposure is likely limited to organizations still running the listed Pegasus Mail versions. The supplied sources do not indicate affected mail servers, other products, or later Pegasus Mail releases. Treat this as a high-priority legacy software cleanup issue if Pegasus Mail is present. The business risk is concentrated on endpoints using vulnerable versions, not the broader email infrastructure based on supplied evidence. Mitigation focus: Inventory endpoints for Pegasus Mail installations and versions.; Prioritize removal or remediation of versions 4.21a through 4.21c and 4.30PB1.; Check Pegasus Mail and Secunia guidance for vendor-confirmed fixes..
