Windows NT 4.0 allows local users to cause a denial of service (crash) via an illegal kernel mode address to the functions (1) GetThreadContext or (2) SetThreadContext.

Windows NT 3.51 and 4.0 allow local users to cause a denial of service (crash) by running a program that creates a large number of locks on a file, which exhausts the NonPagedPool.

Win32k.sys in Windows NT 4.0 before SP2 allows local users to cause a denial of service (crash) by calling certain WIN32K functions with incorrect parameters.

Windows NT 3.51 and 4.0 running WINS (Windows Internet Name Service) allows remote attackers to cause a denial of service (resource exhaustion) via a flood of malformed packets, which causes the server to slow down and fill the event logs with error messages.

Windows NT 4.0 allows local users to cause a denial of service via a user mode application that closes a handle that was opened in kernel mode, which causes a crash when the kernel attempts to close the handle.

When the Ntconfig.pol file is used on a server whose name is longer than 13 characters, Windows NT does not properly enforce policies for global groups, which could allow users to bypass restrictions that were intended by those policies.

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.

Netscape Communicator 4.04 through 4.7 (and possibly other versions) in various UNIX operating systems converts the 0x8b character to a "<" sign, and the 0x9b character to a ">" sign, which could allow remote attackers to attack other clients via cross-site scripting (CSS) in CGI programs that do not filter these characters.

Compaq Integration Maintenance Utility as used in Compaq Insight Manager agent before SmartStart 4.50 modifies the legal notice caption (LegalNoticeCaption) and text (LegalNoticeText) in Windows NT, which could produce a legal notice that is in violation of the security policy.

BMC Patrol component, when installed with Compaq Insight Management Agent 4.23 and earlier, or Management Agents for Servers 4.40 and earlier, creates a PFCUser account with a default password and potentially dangerous privileges.

E-mail client in Softarc FirstClass Internet Server 5.506 and earlier stores usernames and passwords in cleartext in the files (1) home.fc for version 5.506, (2) network.fc for version 3.5, or (3) FCCLIENT.LOG when logging is enabled.

Nosque MsgCore 2.14 stores passwords in cleartext: (1) the administrator password in the AdmPasswd registry key, and (2) user passwords in the Userbase.dbf data file, which could allow local users to gain privileges.

mknod in Linux 2.2 follows symbolic links, which could allow local users to overwrite files or gain privileges.

Directory traversal vulnerability in KVIrc IRC client 0.9.0 with the "Listen to !nick <soundname> requests" option enabled allows remote attackers to read arbitrary files via a .. (dot dot) in a DCC GET request.

ARCAD Systemhaus 0.078-5 installs critical programs and files with world-writeable permissions, which could allow local users to gain privileges by replacing a program with a Trojan horse.

NFS daemon (nfsd.exe) for Omni-NFS/X 6.1 allows remote attackers to cause a denial of service (resource exhaustion) via certain packets, possibly with the Urgent (URG) flag set, to port 111.

Linuxconf on Red Hat Linux 6.0 and earlier does not properly disable PAM-based access to the shutdown command, which could allow local users to cause a denial of service.

Xsession in Red Hat Linux 6.1 and earlier can allow local users with restricted accounts to bypass execution of the .xsession file by starting kde, gnome or anotherlevel from kdm.

PAM configuration file for rlogin in Red Hat Linux 6.1 and earlier includes a less restrictive rule before a more restrictive one, which allows users to access the host via rlogin even if rlogin has been explicitly disabled using the /etc/nologin file.

Auto_FTP.pl script in Auto_FTP 0.2 uses the /tmp/ftp_tmp as a shared directory with insecure permissions, which allows local users to (1) send arbitrary files to the remote server by placing them in the directory, and (2) view files that are being transferred.
