Description:
Secunia Research has discovered two vulnerabilities in Symantec Mail Security, which can be exploited by malicious people to cause a DoS (Denial of Service) on a vulnerable system.
The vulnerabilities are caused due to boundary errors in the SMS Filter Hub service when parsing executable files attached to filtered emails. These can be exploited to cause unhandled access violations by sending a specially crafted executable file attached to an email.
Successful exploitation causes the service to periodically refuse mails and causes the mail queue to backup.
The vulnerabilities are confirmed in Symantec Mail Security for SMTP version 5.0 patch 176 and also reported in the following versions:
* Symantec Mail Security for SMTP (5.0.0 and 5.0.1 versions prior to 5.0.1 patch 181)
* Symantec Mail Security Appliance (5.0.x versions prior to 5.0.0-36)
Solution:
Apply fixes.
Symantec Mail Security for SMTP:
Update to version 5.0.1 and apply patch 181.
Symantec Mail Security Appliance:
Update to version 5.0.0-36 or later.
