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 Javascript "Same Origin Policy" (SOP), as implemented in (1) Netscape, (2) Mozilla, and (3) Internet Explorer, allows a remote web server to access HTTP and SOAP/XML content from restricted sites by mapping the malicious server's parent DNS domain name to the restricted site, loading a page from the restricted site into one frame, and passing the information to the attacker-controlled frame, which is allowed because the document.domain of the two frames matches on the parent domain.
Netscape Mail Notification (nsnotify) utility in Netscape Communicator uses IMAP without SSL, even if the user has set a preference for Communicator to use an SSL connection, allowing a remote attacker to sniff usernames and passwords in plaintext.
When Javascript is embedded within the TITLE tag, Netscape Communicator allows a remote attacker to use the "about" protocol to gain access to browser information.
