SMTP content filter engines, including (1) GFI MailSecurity for Exchange/SMTP before 7.2, (2) InterScan VirusWall before 3.52 build 1494, (3) the default configuration of MIMEDefang before 2.21, and possibly other products, do not detect fragmented emails as defined in RFC2046 ("Message Fragmentation and Reassembly")…

NAI WebShield SMTP 4.5 and possibly 4.5 MR1a does not filter improperly MIME encoded email attachments, which could allow remote attackers to bypass filtering and possibly execute arbitrary code in email clients that process the invalid attachments.

Buffer overflow in the (1) smap/smapd and (2) CSMAP daemons for Gauntlet Firewall 5.0 through 6.0 allows remote attackers to execute arbitrary code via a crafted mail message.

McAfee WebShield SMTP 4.5 allows remote attackers to bypass email content filtering rules by including Extended ASCII characters in name of the attachment.

McAfee WebShield SMTP 4.5 allows remote attackers to cause a denial of service via a malformed recipient field.
