Mozilla based browsers, including Firefox before 1.5.0.10 and 2.x before 2.0.0.2, and SeaMonkey before 1.0.8, allow remote attackers to bypass the same origin policy, steal cookies, and conduct other attacks by writing a URI with a null byte to the hostname (location.hostname) DOM property, due to interactions with DNS resolver code.

Stack-based buffer overflow in Mozilla Firefox allows remote attackers to execute arbitrary code via unspecified vectors involving JavaScript. NOTE: the vendor and original researchers have released a follow-up comment disputing the severity of this issue, in which the researcher states that "we mentioned that there was a previously known Firefox vulnerability that could result in a stack overflow ending up in remote code execution. However, the code we presented did not in fact do this... I have not succeeded in making this code do anything more than cause a crash and eat up system resources"

Multiple unspecified vulnerabilities in Mozilla Firefox have unspecified vectors and impact, as claimed during ToorCon 2006. NOTE: the vendor and original researchers have released a follow-up comment disputing this issue, in which one researcher states that "I have no undisclosed Firefox vulnerabilities. The person who was speaking with me made this claim, and I honestly have no idea if he has them or not.

Cross-domain vulnerability in Mozilla Firefox allows remote attackers to access restricted information from other domains via an object tag with a data parameter that references a link on the attacker's originating site that specifies a Location HTTP header that references the target site, which then makes that content available through the outerHTML attribute of the object. NOTE: this description was based on a report that has since been retracted by the original authors. The authors misinterpreted their test results. Other third parties also disputed the original report. Therefore, this is not a vulnerability. It is being assigned a candidate number to provide a clear indication of its status

Double free vulnerability in the getRawDER function for nsIX509Cert in Firefox allows remote attackers to cause a denial of service (hang) and possibly execute arbitrary code via certain Javascript code.

EvalInSandbox in Mozilla Firefox and Thunderbird before 1.5.0.4 allows remote attackers to gain privileges via javascript that calls the valueOf method on objects that were created outside of the sandbox.

Mozilla Firefox and Thunderbird before 1.5.0.4 allow remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via (1) nested <option> tags in a select tag, (2) a DOMNodeRemoved mutation event, (3) "Content-implemented tree views," (4) BoxObjects, (5) the XBL implementation, (6) an iframe that attempts to remove itself, which leads to memory corruption.

Unspecified vulnerability in Firefox and Thunderbird 1.5 before 1.5.0.2, and SeaMonkey before 1.0.1, allows remote attackers to bypass the js_ValueToFunctionObject check and execute arbitrary code via unknown vectors involving setTimeout and Firefox' ForEach method.

Mozilla Firefox and Thunderbird 1.x before 1.5.0.2 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0.1 allows remote attackers to execute arbitrary code via "an invalid and non-sensical ordering of table-related tags" that results in a negative array index.

Unspecified vulnerability in Firefox and Thunderbird before 1.5.0.2, and SeaMonkey before 1.0.1, allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown attack vectors related to DHTML. NOTE: due to the lack of sufficient public details from the vendor as of 20060413, it is unclear how CVE-2006-1529, CVE-2006-1530, CVE-2006-1531, and CVE-2006-1723 are different.
