Description:
Multiple vulnerabilities have been discovered in Symantec Mail Security for Exchange, 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 version 5.0.7.373. Other versions may also be affected.
NOTE: Version 6.x is not affected.
Solution:
The vendor is currently working on an update.
Disable scanning of message content if enabled.
