content
Microsoft has released MS01-015 ("IE may divulge location to cached
content"). It's possible for a remote Web site to learn the exact
location that Internet Explorer uses to cache Web content. This allows
a malicious Web site to execute various scripting content in the local
system security zone.

Microsoft has released MS01-016 ("Malformed WebDAV request can cause
IIS to exhaust CPU resources"). Repeated malformed PROPFIND WebDAV
requests to an IIS 5 (both 5.0 and 5.1) server cause it to consume
available memory and possibly restart. This can result in a denial of

- --- NetWare News -------------------------------------------------------
*** {01.11.007} NW - Predictable user login with print server UID
A (brief) advisory was released pointing to a vulnerability that would
allow remote attackers to log into an NDS tree using the print server
as the username. By default, NetWare assigns a blank password to print
server user IDs. Print server user IDs also are immune to account
lockout, so it's possible for a remote attacker to brute force the
appropriate password (should one be set).
The vendor has not confirmed this vulnerability; however, there have
been third-party confirmations.

firmware prior to version 8.55 do not correctly disable the Web
configuration interface, even if the configuration says explicitly to
do so. As a result, it's possible for an attacker to reconfigure the
bridge via the Web interface through either locally connected networks
or a wireless link.

*** {01.11.003} Cross - IBM NetCommerce/Net.Data password
retrieval/decryption
IBM's NetCommerce/Net.Data platform (prior to version 5.1) has been
found to use a weak password storage scheme (triple DES with static
key). This allows an attacker, who can retrieve the password hashes, to
decrypt and retrieve the original password. One published method of
remotely retrieving the password hashes was discussed in {01.06.013}
("IBM NetCommerce/Net.Data macro SQL tampering").
IBM has released a statement on the vulnerability. It's available at:

overflows, which lie in the parsing of the map and exec commands, would

buffer overflow in the parsing of configuration files, which could allow
for a local attack.
