5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:N/A:P

Description

Clearswift MAILsweeper for SMTP before 4.3.20 and MAILsweeper for Exchange before 4.3.20 allows remote attackers to cause a denial of service via (1) non-ASCII characters in a reverse DNS lookup result from a Received header, which leads to a Receiver service stop, and (2) unspecified vectors involving malformed messages, which causes "unpredictable behavior" that prevents the Security service from processing more messages.

Affected configurations

• clearswift mailsweeper for exchange (<= 4.3.19) • clearswift mailsweeper for smtp (<= 4.3.19)
