IRC connection tracking helper module in the netfilter subsystem for Linux 2.4.18-pre9 and earlier does not properly set the mask for conntrack expectations for incoming DCC connections, which could allow remote attackers to bypass intended firewall restrictions.

The decompression algorithm in zlib 1.1.3 and earlier, as used in many different utilities and packages, causes inflateEnd to release certain memory more than once (a "double free"), which may allow local and remote attackers to execute arbitrary code via a block of malformed compression data.

Vulnerability in Java Runtime Environment (JRE) allows remote malicious web sites to hijack or sniff a web client's sessions, when an HTTP proxy is being used, via a Java applet that redirects the session to another server, as seen in (1) Netscape 6.0 through 6.1 and 4.79 and earlier, (2) Microsoft VM build 3802 and earlier as used in Internet Explorer 4.x and 5.x, and possibly other implementations that use vulnerable versions of SDK or JDK.

XMLHTTP control in Microsoft XML Core Services 2.6 and later does not properly handle IE Security Zone settings, which allows remote attackers to read arbitrary files by specifying a local file as an XML Data Source.

Buffer overflow in SQL Server 7.0 and 2000 allows remote attackers to execute arbitrary code via a long OLE DB provider name to (1) OpenDataSource or (2) OpenRowset in an ad hoc connection.

SMTP service in Microsoft Windows 2000, Windows XP Professional, and Exchange 2000 allows remote attackers to cause a denial of service via a command with a malformed data transfer (BDAT) request.

SMTP service in (1) Microsoft Windows 2000 and (2) Internet Mail Connector (IMC) in Exchange Server 5.5 does not properly handle responses to NTLM authentication, which allows remote attackers to perform mail relaying via an SMTP AUTH command using null session credentials.

Buffer overflow in SNMP agent service in Windows 95/98/98SE, Windows NT 4.0, Windows 2000, and Windows XP allows remote attackers to cause a denial of service or execute arbitrary code via a malformed management request. NOTE: this candidate may be split or merged with other candidates. This and other PROTOS-related candidates, especially CVE-2002-0012 and CVE-2002-0013, will be updated when more accurate information is available.

Internet Explorer 6.0 and earlier does not properly handle VBScript in certain domain security checks, which allows remote attackers to read arbitrary files.

Windows 2000 allows local users to prevent the application of new group policy settings by opening Group Policy files with exclusive-read access.

Buffer overflow in AuthFilter ISAPI filter on Microsoft Commerce Server 2000 allows remote attackers to execute arbitrary code via long authentication data.

Microsoft Exchange Server 2000 System Attendant gives "Everyone" group privileges to the WinReg key, which could allow remote attackers to read or modify registry keys.

Multiple signedness errors (mixed signed and unsigned numbers) in the I/O functions of rsync 2.4.6, 2.3.2, and other versions allow remote attackers to cause a denial of service and execute arbitrary code in the rsync client or server.

CIPE VPN package before 1.3.0-3 allows remote attackers to cause a denial of service (crash) via a short malformed packet.

Linux kernel, and possibly other operating systems, allows remote attackers to read portions of memory via a series of fragmented ICMP packets that generate an ICMP TTL Exceeded response, which includes portions of the memory in the response packet.

slapd in OpenLDAP 2.0 through 2.0.19 allows local users, and anonymous users before 2.0.8, to conduct a "replace" action on access controls without any values, which causes OpenLDAP to delete non-mandatory attributes that would otherwise be protected by ACLs.

GNU Enscript 1.6.1 and earlier allows local users to overwrite arbitrary files of the Enscript user via a symlink attack on temporary files.

sudo 1.6.0 through 1.6.3p7 does not properly clear the environment before calling the mail program, which could allow local users to gain root privileges by modifying environment variables and changing how the mail program is invoked.

Vulnerability in the XFS file system for SGI IRIX before 6.5.12 allows local users to cause a denial of service (hang) by creating a file that is not properly processed by XFS.

Unknown vulnerability in Mail for SGI IRIX 6.5 through 6.5.15f, and possibly earlier versions, when running with the -R option, allows local and remote attackers to cause a core dump.
