Asterisk Open Source 1.4.5 through 1.4.11, when configured to use an IMAP voicemail storage backend, allows remote attackers to cause a denial of service via an e-mail with an "invalid/corrupted" MIME body, which triggers a crash when the recipient listens to voicemail.

Security readout for executives and security teams

This is a denial-of-service flaw in old Asterisk Open Source voicemail deployments. If Asterisk 1.4.5 through 1.4.11 uses IMAP voicemail storage, a malformed email MIME body can crash the service when the recipient listens to voicemail. Exposure is likely limited to legacy Asterisk 1.4.x systems with IMAP voicemail storage enabled. Systems using other voicemail storage backends are not identified as affected in the provided bundle. Treat this as a targeted reliability risk for legacy voice infrastructure. It is not reported as actively exploited, but affected PBX systems could lose voicemail or call-handling availability until corrected. Mitigation focus: Identify any Asterisk 1.4.5 through 1.4.11 deployments.; Confirm whether IMAP voicemail storage is enabled.; Review Digium AST-2007-021 for the vendor-supported correction path..
