Synopsis :

The remote Windows host contains an application that is affected by a
denial of service vulnerability.

Description :

Symantec Mail Security for SMTP, which provides antispam and antivirus
protection for the IIS SMTP Service, is installed on the remote
Windows host.

The version of Symantec Mail Security for SMTP installed on the remote
host contains boundary errors in its detection of executable packers
in 'libdayzero.dll'. Using a specially crafted email message with an
executable attachment, a remote attacker may be able to leverage this
issue to crash the product's filter hub service (filter-hub.exe) and
cause the mail queue to backup.
