Pack, (2) Windows XP, (3) Windows ME, (4) Lotus Notes R4 through R6 (pre-gold), (5) Verity KeyView, and (6) Stuffit Expander before 7.0.

The HTTP administration interface for HP Procurve 4000M Switch firmware before C.09.16, with stacking features and remote administration enabled, does not authenticate requests to reset the device, which allows remote attackers to cause a denial of service via a direct request to the device_reset CGI program.

Directory traversal vulnerability in the CGIServlet for Jetty HTTP server before 4.1.0 allows remote attackers to execute arbitrary commands via ..\ (dot-dot backslash) sequences in an HTTP request to the cgi-bin directory.

The getmxrecord function in Fetchmail 6.0.0 and earlier does not properly check the boundary of a particular malformed DNS packet from a malicious DNS server, which allows remote attackers to cause a denial of service (crash) when Fetchmail attempts to read data beyond the expected boundary.

The handle_var_requests function in snmp_agent.c for the SNMP daemon in the Net-SNMP (formerly ucd-snmp) package 5.0.1 through 5.0.5 allows remote attackers to cause a denial of service (crash) via a NULL dereference.

Apache 2.0.42 allows remote attackers to view the source code of a CGI script via a POST request to a directory with both WebDAV and CGI enabled.

anlgform.pl in Analog before 5.23 does not restrict access to the PROGRESSFREQ progress update command, which allows remote attackers to cause a denial of service (disk consumption) by using the command to report updates more frequently and fill the web server error log.

IBM Websphere 4.0.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via an HTTP request with long HTTP headers, such as "Host".

The installation procedure for Invision Board suggests that users install the phpinfo.php program under the web root, which leaks sensitive information such as absolute pathnames, OS information, and PHP settings.

The default servlet (org.apache.catalina.servlets.DefaultServlet) in Tomcat 4.0.4 and 4.1.10 and earlier allows remote attackers to read source code for server files via a direct request to the servlet.

The BIND 4 and BIND 8.2.x stub resolver libraries, and other libraries such as glibc 2.2.5 and earlier, libc, and libresolv, use the maximum buffer size instead of the actual size when processing a DNS response, which causes the stub resolvers to read past the actual boundary ("read buffer overflow"), allowing remote attackers to cause a denial of service (crash).

An input validation error in the Sun Microsystems RPC library Services for Unix 3.0 Interix SD, as implemented on Microsoft Windows NT4, 2000, and XP, allows remote attackers to cause a denial of service via malformed fragmented RPC client packets, aka "Denial of service by sending an invalid RPC request."

The Sun Microsystems RPC library Services for Unix 3.0 Interix SD, as implemented on Microsoft Windows NT4, 2000, and XP, allows remote attackers to cause a denial of service (service hang) via malformed packet fragments, aka "Improper parameter size check leading to denial of service."

The Compressed Folders feature in Microsoft Windows 98 with Plus! Pack, Windows Me, and Windows XP does not properly check the destination folder during the decompression of ZIP files, which allows attackers to place an executable file in a known location on a user's system, aka "Incorrect Target Path for Zipped File Decompression."

The Web Reports Server for SurfControl SuperScout WebFilter allows remote attackers to cause a denial of service (CPU consumption) via large GET requests, possibly due to a buffer overflow.

Directory traversal vulnerability in GNU tar 1.13.19 through 1.13.25, and possibly later versions, allows attackers to overwrite arbitrary files during archive extraction via a (1) "/.." or (2) "./.." string, which removes the leading slash but leaves the "..", a variant of CVE-2001-1267.

The default configuration of Cisco Unity 2.x and 3.x does not block international operator calls in the predefined restriction tables, which could allow authenticated users to place international calls using call forwarding.

The Remote Desktop Sharing (RDS) Screen Saver Protection capability for Microsoft NetMeeting 3.01 through SP2 (4.4.3396) allows attackers with physical access to hijack remote sessions by entering certain logoff or shutdown sequences (such as CTRL-ALT-DEL) and canceling out of the resulting user confirmation prompts, such as when the remote user is editing a document.

Buffer overflow in MySQL daemon (mysqld) before 3.23.50, and 4.0 beta before 4.02, on the Win32 platform, allows local users to execute arbitrary code via a long "datadir" parameter in the my.ini initialization file, whose permissions on Windows allow Full Control to the Everyone group.
