CyberRota Analysis
AI-GeneratedThis vulnerability affects mail servers that process IMAP THREAD commands, allowing an attacker to craft a malicious message header that leads to excessive CPU consumption, potentially resulting in service degradation or denial of service. Organizations that manage email services should prioritize monitoring for unusual CPU activity and ensure they are using updated, non-vulnerable software versions to mitigate this risk. Although no public exploits are known, proactive measures are essential to maintain service integrity.

Original NVD Description
An attacker that can send mail to a user can craft a message header that makes the IMAP THREAD command consume CPU disproportionate to the size of the message. When a mail client issues a THREAD command on the affected mailbox, this can cause degradation or denial of service for IMAP. Monitor system for abnormal CPU usage, kill the offending process and remove the offending message from the affected mailbox. Update to non-vulnerable version. No publicly available exploits are known.
