Mozilla has rolled out an update to its Firefox browser that patches a critical zero-day security vulnerability.<\/p>\n
A zero-day vulnerability is a security flaw that the software vendor is aware of, but for which there is no immediate available fix.<\/p>\n
This particular Firefox flaw could potentially let attackers take control of targeted computers.<\/p>\n
Chinese cybersecurity firm Qihoo first identified and reported the bug, after which Mozilla published an advisory<\/strong><\/a> for the vulnerability in which it labelled the issue as critical.<\/p>\n “Incorrect alias information in IonMonkey JIT compiler for setting array elements could lead to a type confusion,” Mozilla stated.<\/p>\n ZDNet<\/strong><\/a> describes a type confusion as a type of “memory bug where a memory input is initially allocated as one type but gets switched to another type during manipulation.”<\/p>\n The result could give malicious actors the ability to execute code or crash a compromised system.<\/p>\n Both Mozilla and the US Cybersecurity and Infrastructure Security Agency<\/strong><\/a> confirmed that instances of the exploit had been observed in the wild.<\/p>\n No specific details about the exploits were made available, possibly as a measure to decrease the likelihood of further attacks.<\/p>\n The release of Firefox version 72.0.1 fixes the issue.<\/p>\n It is recommended that Firefox users update to the latest version of the browser to prevent falling victim to the exploit.<\/p>\n The latest bug follows two previous Firefox zero-day vulnerabilities, which attackers attempted to exploit to install backdoors on Macs belonging to cryptocurrency exchange Coinbase.<\/p>\n Mozilla has rolled out an update to the Firefox browser that patches a critical security vulnerability.<\/p>\n","protected":false},"author":23,"featured_media":282307,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[49899,981,975],"class_list":["post-334588","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-security","tag-browser-security","tag-firefox","tag-mozilla"],"_links":{"self":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/334588"}],"collection":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/users\/23"}],"replies":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/comments?post=334588"}],"version-history":[{"count":2,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/334588\/revisions"}],"predecessor-version":[{"id":334618,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/posts\/334588\/revisions\/334618"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media\/282307"}],"wp:attachment":[{"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/media?parent=334588"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/categories?post=334588"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mybroadband.co.za\/news\/wp-json\/wp\/v2\/tags?post=334588"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Known exploits<\/h3>\n
