Some vulnerabilities have been reported in Mozilla Firefox, which can be exploited by malicious people to disclose sensitive information, bypass certain security restrictions, or compromise a user's system.
1) An error in the processing of ".url" shortcuts can be exploited to obtain sensitive information from the local cache.
2) An error in the handling of HTTP redirect requests can be exploited to bypass the same-origin policy and access potential sensitive information stored in images in another domain.
4) An error when locking a non-native object can be exploited to cause a crash via a web page assigning a specially crafted value to the "window.__proto__.__proto__" object.
5) An error in the browser engine can be exploited to cause a memory corruption.
Successful exploitation of vulnerabilities #3-#6 may allow execution of arbitrary code.
8) An error in the processing of the "http-index-format" MIME type can be exploited to execute arbitrary code via a specially crafted 200 header line included in an HTTP index response.
9) An error in the DOM constructing code can be exploited to dereference uninitialized memory and potentially execute arbitrary code by modifying certain properties of a file input element before the element has finished initializing.
12) An error exists when parsing the default XML namespace of an E4X document. This can be exploited to inject arbitrary XML code via a specially crafted namespace containing quote characters.
The vulnerabilities are reported in versions prior to 18.104.22.168.
