Netscape 6 and 8 allows remote attackers to cause a denial of service (memory consumption) via a large integer value for the length property of a Select object, a related issue to CVE-2009-1692.

Mozilla 1.9 M8 and earlier, Mozilla Firefox 2 before 2.0.0.15, SeaMonkey 1.1.5 and other versions before 1.1.10, Netscape 9.0, and other Mozilla-based web browsers, when a user accepts an SSL server certificate on the basis of the CN domain name in the DN field, regard the certificate as also accepted for all domain names in subjectAltName:dNSName fields, which makes it easier for remote attackers to trick a user into accepting an invalid certificate for a spoofed web site.

Multiple argument injection vulnerabilities in Netscape Navigator 9 allow remote attackers to execute arbitrary commands via a NULL byte (%00) and shell metacharacters in a (1) mailto, (2) nntp, (3) news, (4) snews, or (5) telnet URI, a similar issue to CVE-2007-3670.

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.

AcroPDF.DLL in Adobe Reader 8.0, when accessed from Mozilla Firefox, Netscape, or Opera, allows remote attackers to cause a denial of service (unspecified resource consumption) via a .pdf URL with an anchor identifier that begins with search= followed by many %n sequences, a different vulnerability than CVE-2006-6027 and CVE-2006-6236.

The (1) Password Manager in Mozilla Firefox 2.0, and 1.5.0.8 and earlier; and the (2) Passcard Manager in Netscape 8.1.2 and possibly other versions, do not properly verify that an ACTION URL in a FORM element containing a password INPUT element matches the web site for which the user stored a password, which allows remote attackers to obtain passwords via a password INPUT element on a different web page located on the web site intended for this password.

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.

Mozilla Firefox 1.5.0.4, 2.0.x before 2.0.0.8, Mozilla Suite 1.7.13, Mozilla SeaMonkey 1.0.2 and other versions before 1.1.5, and Netscape 8.1 and earlier allow user-assisted remote attackers to read arbitrary files by tricking a user into typing the characters of the target filename in a text box and using the OnKeyDown, OnKeyPress, and OnKeyUp Javascript keystroke events to change the focus and cause those characters to be inserted into a file upload input control, which can then upload the file when the user submits the form.

Mozilla Suite 1.7.13, Mozilla Firefox 1.5.0.3 and possibly other versions before before 1.8.0, and Netscape 7.2 and 8.1, and possibly other versions and products, allows remote user-assisted attackers to obtain information such as the installation path by causing exceptions to be thrown and checking the message contents.

Mozilla Firefox 1.5.0.2 and possibly other versions before 1.5.0.4, Netscape 8.1, 8.0.4, and 7.2, and K-Meleon 0.9.13 allows user-assisted remote attackers to open local files via a web page with an IMG element containing a SRC attribute with a non-image file:// URL, then tricking the user into selecting View Image for the broken image, as demonstrated using a .wma file to launch Windows Media Player, or by referencing an "alternate web page."

Mozilla Firefox 1.5, Netscape 8.0.4 and 7.2, and K-Meleon before 0.9.12 allows remote attackers to cause a denial of service (CPU consumption and delayed application startup) via a web site with a large title, which is recorded in history.dat but not processed efficiently during startup. NOTE: despite initial reports, the Mozilla vendor does not believe that this issue can be used to trigger a crash or buffer overflow in Firefox. Also, it has been independently reported that Netscape 8.1 does not have this issue.

The find_replen function in jsstr.c in the Javascript engine for Mozilla Suite 1.7.6, Firefox 1.0.1 and 1.0.2, and Netscape 7.2 allows remote attackers to read portions of heap memory in a Javascript string via the lambda replace method.

Firefox before 1.0.3, Mozilla Suite before 1.7.7, and Netscape 7.2 allows remote attackers to execute arbitrary script and code via a new search plugin using sidebar.addSearchEngine, aka "Firesearching 1."

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."

Netscape 7.x to 7.2, and possibly other versions, allows remote attackers to spoof arbitrary web sites by injecting content from one window into a target window whose name is known but resides in a different domain, as demonstrated using a pop-up window on a trusted web site, aka the "window injection" vulnerability.

Integer overflow in the bitmap (BMP) decoder for Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allow remote attackers to execute arbitrary code via wide bitmap files that trigger heap-based buffer overflows.

The Apple Java plugin, as used in Netscape 7.1 and 7.2, Mozilla 1.7.2, and Firefox 0.9.3 on MacOS X 10.3.5, when tabbed browsing is enabled, does not properly handle SetWindow(NULL) calls, which allows Java applets from one tab to draw to other tabs and facilitates phishing attacks that spoof tabs.

Mozilla Firefox before the Preview Release, Mozilla before 1.7.3, and Thunderbird before 0.8 allows remote attackers to perform cross-domain scripting and possibly execute arbitrary code by convincing a user to drag and drop javascript: links to a frame or page in another domain.

Integer overflow in the SOAPParameter object constructor in (1) Netscape version 7.0 and 7.1 and (2) Mozilla 1.6, and possibly earlier versions, allows remote attackers to execute arbitrary code.

Netscape Navigator 7.1 allows remote attackers to spoof a legitimate URL in the status bar via A HREF tags with modified "alt" values that point to the legitimate site, combined with an image map whose href points to the malicious site, which facilitates a "phishing" attack.
