Command execution via shell metachars in INN daemon (innd) 1.5 using "newgroup" and "rmgroup" control messages, and others.

Argument injection vulnerability in Microsoft Internet Explorer, when running on systems with Netscape installed and certain URIs registered, allows remote attackers to conduct cross-browser scripting attacks and execute arbitrary commands via shell metacharacters in a -chrome argument to the navigatorurl URI, which are inserted into the command line that is created when invoking netscape.exe, a related issue to CVE-2007-3670. NOTE: there has been debate about whether the issue is in Internet Explorer or Netscape. As of 20070713, it is CVE's opinion that IE appears to not properly delimit the URL argument when invoking Netscape; this issue could arise with other protocol handlers in IE.

Concurrency vulnerability in Mozilla Firefox 1.5.0.6 and earlier allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via multiple Javascript timed events that load a deeply nested XML file, followed by redirecting the browser to another page, which leads to a concurrency failure that causes structures to be freed incorrectly, as demonstrated by (1) ffoxdie and (2) ffoxdie3. NOTE: it has been reported that Netscape 8.1 and K-Meleon 1.0.1 are also affected by ffoxdie. Mozilla confirmed to CVE that ffoxdie and ffoxdie3 trigger the same underlying vulnerability. NOTE: it was later reported that Firefox 2.0 RC2 and 1.5.0.7 are also affected.

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.

Buffer overflow in Netscape Navigator/Communicator 4.7 for Windows 95 and Windows 98 allows remote attackers to cause a denial of service, and possibly execute arbitrary commands, via a long argument after the ? character in a URL that references an .asp, .cgi, .html, or .pl file.

Buffer overflow in Netscape Enterprise Server and FastTrask Server allows remote attackers to gain privileges via a long HTTP GET request.

Firefox before 1.0.3, Mozilla Suite before 1.7.7, and Netscape 7.2 allows remote attackers to replace existing search plugins with malicious ones using sidebar.addSearchEngine and the same filename as the target engine, which may not be displayed in the GUI, which could then be used to execute malicious script, aka "Firesearching 2."
