Buffer overflow in SMB (Server Message Block) protocol in Microsoft Windows NT, Windows 2000, and Windows XP allows attackers to cause a denial of service (crash) via a SMB_COM_TRANSACTION packet with a request for the (1) NetShareEnum, (2) NetServerEnum2, or (3) NetServerEnum3, aka "Unchecked Buffer in Network Share Provider Can Lead to Denial of Service".

Microsoft Internet Explorer 5.5 and 6.0 does not properly verify the domain of a frame within a browser window, which allows remote attackers to read client files or invoke executable objects via the Object tag, aka "Cross Domain Verification in Object Tag."

Microsoft Internet Explorer 5.01, 5.5, and 6.0 allows remote attackers to misrepresent the source of a file in the File Download dialogue box to trick users into thinking that the file type is safe to download, aka "File Origin Spoofing."

Microsoft SQL Server 7.0 and 2000 installs with weak permissions for extended stored procedures that are associated with helper functions, which could allow unprivileged users, and possibly remote attackers, to run stored procedures with administrator privileges via (1) xp_execresultset, (2) xp_printstatements, or (3) xp_displayparamstmt.

A handler routine for the Network Connection Manager (NCM) in Windows 2000 allows local users to gain privileges via a complex attack that causes the handler to run in the LocalSystem context with user-specified code.

Web authoring command in Microsoft Content Management Server (MCMS) 2001 allows attackers to authenticate and upload executable content, by modifying the upload location, aka "Program Execution via MCMS Authoring Function."

PHP 4.2.0 and 4.2.1 allows remote attackers to cause a denial of service and possibly execute arbitrary code via an HTTP POST request with certain arguments in a multipart/form-data form, which generates an error condition that is not properly handled and causes improper memory to be freed.

Format string vulnerability in crontab for SCO OpenServer 5.0.5 and 5.0.6 allows local users to gain privileges via format string specifiers in the file name argument.

Vulnerability in Squid before 2.4.STABLE6 related to proxy authentication credentials may allow remote web sites to obtain the user's proxy login and password.

FTP proxy in Squid before 2.4.STABLE6 does not compare the IP addresses of control and data connections with the FTP server, which allows remote attackers to bypass firewall rules or spoof FTP server responses.

Buffer overflows in Squid before 2.4.STABLE6 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code (1) via the MSNT auth helper (msnt_auth) when using denyusers or allowusers files, (2) via the gopher client, or (3) via the FTP server directory listing parser when HTML output is generated.

Entrust Authority Security Manager (EASM) 6.0 does not properly require multiple master users to change the password of a master user, which could allow a master user to perform operations that require multiple authorizations.

Unknown vulnerability in Cluster Interconnect for HP TruCluster Server 5.0A, 5.1, and 5.1A may allow local and remote attackers to cause a denial of service.
