Qbik Wingate 4.0.1

Heap-based buffer overflow in the IMAP service in Qbik WinGate 6.2.2.1137 and earlier allows remote authenticated users to cause a denial of service (resource exhaustion) or possibly execute arbitrary code via a long argument to the LIST command. NOTE: some of these details are obtained from third party information.

Multiple implementations of the DNS protocol, including (1) Poslib 1.0.2-1 and earlier as used by Posadis, (2) Axis Network products before firmware 3.13, and (3) Men & Mice Suite 2.2x before 2.2.3 and 3.5.x before 3.5.2, allow remote attackers to cause a denial of service (CPU and network bandwidth consumption) by triggering a communications loop via (a) DNS query packets with localhost as a spoofed source address, or (b) a response packet that triggers a response packet.

Directory traversal vulnerability in the logfile service of Wingate 4.1 Beta A and earlier allows remote attackers to read arbitrary files via a .. (dot dot) attack via an HTTP GET request that uses encoded characters in the URL.
