The component for the Virtual DOS Machine (VDM) subsystem in Windows NT 4.0 and Windows 2000 does not properly validate system structures, which allows local users to access protected kernel memory and execute arbitrary code.

The NtSetLdtEntries function in the programming interface for the Local Descriptor Table (LDT) in Windows NT 4.0 and Windows 2000 allows local attackers to gain access to kernel memory and execute arbitrary code via an expand-down data segment descriptor descriptor that points to protected memory.

Windows XP allows local users to execute arbitrary programs by creating a task at an elevated privilege level through the eventtriggers.exe command-line tool or the Task Scheduler service, aka "Windows Management Vulnerability."

The Utility Manager in Microsoft Windows 2000 executes winhlp32.exe with system privileges, which allows local users to execute arbitrary code via a "Shatter" style attack using a Windows message that accesses the context sensitive help button in the GUI, as demonstrated using the File Open dialog in the Help window, a different vulnerability than CVE-2004-0213.

Stack-based buffer overflow in the RT3 plugin, as used in RealPlayer 8, RealOne Player, RealOne Player 10 beta, and RealOne Player Enterprise, allows remote attackers to execute arbitrary code via a malformed .R3T file.

Help and Support Center in Microsoft Windows XP SP1 does not properly validate HCP URLs, which allows remote attackers to execute arbitrary code via quotation marks in an hcp:// URL, which are not quoted when constructing the argument list to HelpCtr.exe.

CVS before 1.11 allows CVS clients to read arbitrary files via ..

Racoon before 20040408a allows remote attackers to cause a denial of service (memory consumption) via an ISAKMP packet with a large length field.

Mailman before 2.0.13 allows remote attackers to cause a denial of service (crash) via an email message with an empty subject field.

The ext3 code in Linux 2.4.x before 2.4.26 does not properly initialize journal descriptor blocks, which causes an information leak in which in-memory data is written to the device for the ext3 file system, which allows privileged users to obtain portions of kernel memory by reading the raw device.

Format string vulnerabilities in the (1) die or (2) log_event functions for ssmtp before 2.50.6 allow remote mail relays to cause a denial of service and possibly execute arbitrary code.

The Microsoft Secure Sockets Layer (SSL) library, as used in Windows 2000, Windows XP, and Windows Server 2003, allows remote attackers to cause a denial of service via malformed SSL messages.

An Activation function in the RPCSS Service involved with DCOM activation for Microsoft Windows 2000, XP, and 2003 allows remote attackers to cause a denial of service (memory consumption) via an activation request with a large length field.

Buffer overflow in the COM Internet Services and in the RPC over HTTP Proxy components for Microsoft Windows NT Server 4.0, NT 4.0 Terminal Server Edition, 2000, XP, and Server 2003 allows remote attackers to cause a denial of service via a crafted request.

Unknown vulnerability in the Local Security Authority Subsystem Service (LSASS) in Windows 2000 domain controllers allows remote attackers to cause a denial of service via a crafted LDAP message.

Vignette Story Server 4.1 and 6.0 allows remote attackers to obtain sensitive information via a request that contains a large number of '"' (double quote) and and '>' characters, which causes the TCL interpreter to crash and include stack data in the output.

x11.c in xonix 1.4 and earlier uses the current working directory to find and execute the rmail program, which allows local users to execute arbitrary code by modifying the path to point to a malicious rmail program.

Buffer overflow in the ISO9660 file system component for Linux kernel 2.4.x, 2.5.x and 2.6.x, allows local users with physical access to overflow kernel memory and execute arbitrary code via a malformed CD containing a long symbolic link entry.

The HTML form upload capability in ColdFusion MX 6.1 does not reclaim disk space if an upload is interrupted, which allows remote attackers to cause a denial of service (disk consumption) by repeatedly uploading files and interrupting the uploads before they finish.

The client for CVS before 1.11 allows a remote malicious CVS server to create arbitrary files using certain RCS diff files that use absolute pathnames during checkouts or updates, a different vulnerability than CVE-2004-0405.

The DCOM RPC interface for Microsoft Windows NT 4.0, 2000, XP, and Server 2003 allows remote attackers to cause network communications via an "alter context" call that contains additional data, aka the "Object Identity Vulnerability."

The mysqld_multi script in MySQL allows local users to overwrite arbitrary files via a symlink attack.

The JFS file system code in Linux 2.4.x has an information leak in which in-memory data is written to the device for the JFS file system, which allows local users to obtain sensitive information by reading the raw device.

The OSS code for the Sound Blaster (sb16) driver in Linux 2.4.x before 2.4.26, when operating in 16 bit mode, does not properly handle certain sample sizes, which allows local users to cause a denial of service (crash) via a sample with an odd number of bytes.

The XFS file system code in Linux 2.4.x has an information leak in which in-memory data is written to the device for the XFS file system, which allows local users to obtain sensitive information by reading the raw device.
