Internet Explorer 5.5 and 6 with the Q312461 (MS01-055) patch modifies the HTTP_USER_AGENT (UserAgent) information that indicates that the patch has been installed, which could allow remote malicious web sites to more easily identify and exploit vulnerable clients.

Internet Explorer 5.5 allows remote attackers to bypass security restrictions via malformed URLs that contain dotless IP addresses, which causes Internet Explorer to process the page in the Intranet Zone, which may have fewer security restrictions, aka the "Zone Spoofing Vulnerability variant" of CVE-2001-0664.

Internet Explorer 5.5 and 6.0 allows remote attackers to read and modify user cookies via Javascript, aka the "Second Cookie Handling Vulnerability."

The rendering engine in Internet Explorer determines the MIME type independently of the type that is specified by the server, which allows remote servers to automatically execute script which is placed in a file whose MIME type does not normally support scripting, such as text (.txt), JPEG (.jpg), etc.

Internet Explorer 6 and earlier, when used with the Telnet client in Services for Unix (SFU) 2.0, allows remote attackers to execute commands by spawning Telnet with a log file option on the command line and writing arbitrary code into an executable file which is later executed, aka a new variant of the Telnet Invocation vulnerability as described in CVE-2001-0150.

Outlook Web Access (OWA) in Microsoft Exchange 2000 allows an authenticated user to cause a denial of service (CPU consumption) via a malformed OWA request for a deeply nested folder within the user's mailbox.

Internet Explorer 5.5 and 5.01 allows remote attackers to bypass security restrictions via malformed URLs that contain dotless IP addresses, which causes Internet Explorer to process the page in the Intranet Zone, which may have fewer security restrictions, aka the "Zone Spoofing vulnerability."
