Rit Research Labs The Bat! 1.51 for Windows allows a remote attacker to cause a denial of service by sending an email to a user's account containing a carriage return <CR> that is not followed by a line feed <LF>.

A buffer overflow in reggo.dll file used by Trend Micro InterScan VirusWall prior to 3.51 build 1349 for Windows NT 3.5 and InterScan WebManager 1.2 allows a local attacker to execute arbitrary code.

Broker FTP server 5.9.5 for Windows NT and 9x allows a remote attacker to retrieve privileged web server system information by (1) issuing a CD command (CD C:) followed by the LS command, (2) specifying arbitrary paths in the UNC format (\\computername\sharename).

Windows NT allows remote attackers to list all users in a domain by obtaining the domain SID with the LsaQueryInformationPolicy policy function via a null session and using the SID to list the users.
