CVE-2007-3443: The Research in Motion BlackBerry 7270 before 4.0 SP1 Bundle 108 does not properly manage transaction state...

The Research in Motion BlackBerry 7270 before 4.0 SP1 Bundle 108 does not properly manage transaction states, which allows remote attackers to cause a denial of service (temporary device hang) by sending a certain SIP INVITE message, but not providing an ACK when the call is answered.

Security readout for executives and security teams

This issue affected legacy BlackBerry 7270 devices before 4.0 SP1 Bundle 108. A remote SIP call could leave the device temporarily hung if the call transaction was not completed correctly. Business impact is availability disruption for a niche, obsolete device class, not data theft based on the provided sources. Exposure is likely limited to organizations still operating BlackBerry 7270 devices with firmware earlier than 4.0 SP1 Bundle 108 and SIP calling enabled or reachable. Treat as low-to-moderate priority unless legacy BlackBerry 7270 devices support critical voice workflows. The main concern is short-term service disruption, not confirmed compromise. Mitigation focus: Inventory BlackBerry 7270 devices and record firmware bundle versions.; Update affected devices to 4.0 SP1 Bundle 108 or later if vendor guidance supports it.; If updates are unavailable, consult BlackBerry guidance for compensating controls..
