Weak proxy objects have weak references on multiple threads when they should only have them on one, resulting in incorrect memory usage and corruption, which leads to potentially exploitable crashes. Note: This issue only affects Firefox for Android. Other operating systems are not affected. This vulnerability affects Firefox < 51.

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"

Mozilla Firefox 1.5.0.6 allows remote attackers to execute arbitrary JavaScript in the context of the browser's session with an arbitrary intranet web server, by hosting script on an Internet web server that can be made inaccessible by the attacker and that has a domain name under the attacker's control, which can force the browser to drop DNS pinning and perform a new DNS query for the domain name after the script is already running.

Bugzilla 2.14 before 2.14.2, and 2.16 before 2.16rc2, does not properly handle URL-encoded field names that are generated by some browsers, which could cause certain fields to appear to be unset, which has the effect of removing group permissions on bugs when buglist.cgi is provided with the encoded field names.

Mozilla Firefox 1.5 before 1.5.0.5, Thunderbird before 1.5.0.5, and SeaMonkey before 1.0.3 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via simultaneous XPCOM events, which causes a timer object to be deleted in a way that triggers memory corruption.

Mozilla Firefox 1.5 before 1.5.0.5 and SeaMonkey before 1.0.3 does not properly clear a JavaScript reference to a frame or window, which leaves a pointer to a deleted object that allows remote attackers to execute arbitrary native code.

Certain privileged UI code in Mozilla Firefox and Thunderbird before 1.5.0.4 calls content-defined setters on an object prototype, which allows remote attackers to execute code at a higher privilege than intended.
