CyberRota Analysis
AI-GeneratedThis vulnerability affects email systems that process messages with excessively large headers, potentially leading to denial of service by exhausting memory resources when parsing such messages. Users who receive crafted emails with numerous email addresses or MIME parameters may experience crashes in their email clients, particularly when accessing messages via IMAP. Organizations relying on email services should prioritize addressing this issue to prevent service disruptions for their users.

Original NVD Description
An attacker that can send mail to a user can craft a message whose headers contain a very large number of email addresses or MIME parameters, which causes excessive memory usage when the message is later parsed. The message is still delivered, but reading it over IMAP can exhaust the memory limit of the process and terminate it, causing denial of service for the affected user. Update to non-vulnerable version. No publicly available exploits are known.
