Description:
Some vulnerabilities have been reported in MAILsweeper for SMTP/Exchange, which can be exploited by malicious people to bypass certain security restrictions and potentially cause a DoS (Denial of Service).
1) An error exists within the handling of messages that specify a non-existent character set. This can be exploited to bypass text analysis.
2) An error exists within the handling of reverse DNS lookups when the "Received" header in a message includes non-ASCII characters. This can be exploited to cause the Receiver service to stop processing messages.
3) An error exists within the handling of certain malformed messages. This can be exploited to cause the Security service to stop processing messages.
The vulnerabilities have been reported in the following products:
* MAILsweeper for SMTP version 4.3.19
* MIMEsweeper for Exchange version 4.3.19
Prior versions may also be affected.
