-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of IPSwitch IMail List Mailer. Authentication
is not required to exploit this vulnerability.
The specific flaw exists within imailsrv.exe which is invoked to handle
messages sent to the imailsrv. When a message contains multiple
"Reply-To:" headers the imailsrv.exe process concatenates these into a
single fixed length buffer on the stack. No validation of the data or
data length is done. A remote attacker can exploit this vulnerability to
execute arbitrary code under the context of the SYSTEM user.
