Multiple remote denial of service vulnerabilities affect the Quarantine component of Symantec's Brightmail AntiSpam. These issues are due to a failure of the application to properly handle quarantined mail notifications and exceptional conditions in message processing. The first issue arises when an excessively large number of spam messages are held in a user's Quarantine folder. The second issue presents itself when the Notifier encounters SMTP errors during notifications. An attacker may leverage these issues to cause the affected component to crash, disabling spam notifications and potentially allowing spam to bypass the filtering process.
