Vulnerabilidades

Windows 95, Windows 98, Windows 2000, Windows NT 4.0, and Terminal Server systems allow a remote attacker to cause a denial of service by sending a large number of identical fragmented IP packets, aka jolt2 or the "IP Fragment Reassembly" vulnerability.

The default configuration of SYSKEY in Windows 2000 stores the startup key in the registry, which could allow an attacker tor ecover it and use it to decrypt Encrypted File System (EFS) data.

NTMail 5.x allows network users to bypass the NTMail proxy restrictions by redirecting their requests to NTMail's web configuration server.

The Windows 2000 domain controller allows a malicious user to modify Active Directory information by modifying an unprotected attribute, aka the "Mixed Object Access" vulnerability.

The default configuration for the domain name resolver for Microsoft Windows 98, NT 4.0, 2000, and XP sets the QueryIpMatching parameter to 0, which causes Windows to accept DNS updates from hosts that it did not query, which allows remote attackers to poison the DNS cache.

A Windows NT system does not clear the system page file during shutdown, which might allow sensitive information to be recorded.

When an administrator in Windows NT or Windows 2000 changes a user policy, the policy is not properly updated if the local ntconfig.pol is not writable by the user, which could allow local users to bypass restrictions that would otherwise be enforced by the policy, possibly by changing the policy file to be read-only.

NTMail does not disable the VRFY command, even if the administrator has explicitly disabled it.

Buffer overflow in Microsoft Rich Text Format (RTF) reader allows attackers to cause a denial of service via a malformed control word.

DHCP clients with ICMP Router Discovery Protocol (IRDP) enabled allow remote attackers to modify their default routes.
