Symantec Mail Security for SMTP 4.x

DESCRIPTION:
Multiple vulnerabilities have been discovered in Symantec Mail
Security for SMTP, which can be exploited by malicious people to
cause a DoS (Denial of Service) and compromise a vulnerable system.

The vulnerabilities are caused due to various errors within certain
third-party file viewers and can be exploited to cause buffer
overflows when a specially crafted file is checked.

The vulnerabilities are related to:
SA27304

Successful exploitation allows execution of arbitrary code, but
requires that e.g. a policy is setup for scanning the contents of
messages.

The vulnerabilities are confirmed in Symantec Mail Security for SMTP
version 5.0.1 without Patch 181 and 182. Prior versions and other
products may also be affected.

SOLUTION:
The vulnerabilities have been silently fixed with Patch 181 and 182
for version 5.0.1.
