CVE-2019-17023 [MEDIUM] CVE-2019-17023: firefox - After a HelloRetryRequest has been sent, the client may negotiate a lower protoc... After a HelloRetryRequest has been sent, the client may negotiate a lower protocol that TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data records will be ignored. This vulnerability affects Firefox < 72. Scope: local sid: resolved (fixed in 72.0-1)

CVE-2019-11744 [MEDIUM] CVE-2019-11744: firefox - Some HTML elements, such as &lt;title&gt; and &lt;textarea&gt;, can contain lite... Some HTML elements, such as and , can contain literal angle brackets without treating them as markup. It is possible to pass a literal closing tag to .innerHTML on these elements, and subsequent content after that will be parsed as if it were outside the tag. This can lead to XSS if a site does not filter user input as strictly for these elements as it does for ot

CVE-2019-17002 [MEDIUM] CVE-2019-17002: firefox - If upgrade-insecure-requests was specified in the Content Security Policy, and a... If upgrade-insecure-requests was specified in the Content Security Policy, and a link was dragged and dropped from that page, the link was not upgraded to https.

CVE-2019-17020 [MEDIUM] CVE-2019-17020: firefox - If an XML file is served with a Content Security Policy and the XML file include... If an XML file is served with a Content Security Policy and the XML file includes an XSL stylesheet, the Content Security Policy will not be applied to the contents of the XSL stylesheet. If the XSL sheet e.g. includes JavaScript, it would bypass any of the restrictions of the Content Security Policy applied to the XML document. This vulnerability affects Firefox

CVE-2019-11765 [MEDIUM] CVE-2019-11765: firefox - A compromised content process could send a message to the parent process that wo... A compromised content process could send a message to the parent process that would cause the 'Click to Play' permission prompt to be shown. However, due to lack of validation from the parent process, if the user accepted the permission request an attacker-controlled permission would be granted rather than the 'Click to Play' permission. This vulnerability affects

CVE-2019-11718 [MEDIUM] CVE-2019-11718: firefox - Activity Stream can display content from sent from the Snippet Service website. ... Activity Stream can display content from sent from the Snippet Service website. This content is written to innerHTML on the Activity Stream page without sanitization, allowing for a potential access to other information available to the Activity Stream, such as browsing history, if the Snipper Service were compromised. This vulnerability affects Firefox < 68. Scop

CVE-2019-17016 [MEDIUM] CVE-2019-17016: firefox - When pasting a &lt;style&gt; tag from the clipboard into a rich text editor, the... When pasting a tag from the clipboard into a rich text editor, the CSS sanitizer incorrectly rewrites a @namespace rule. This could allow for injection into certain types of websites resulting in data exfiltration. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72. Scope: local sid: resolved (fixed in 72.0-1)

CVE-2019-11697 [MEDIUM] CVE-2019-11697: firefox - If the ALT and "a" keys are pressed when users receive an extension installation... If the ALT and "a" keys are pressed when users receive an extension installation prompt, the extension will be installed without the install prompt delay that keeps the prompt visible in order for users to accept or decline the installation. A malicious web page could use this with spoofing on the page to trick users into installing a malicious extension. This vul

CVE-2019-9807 [MEDIUM] CVE-2019-9807: firefox - When arbitrary text is sent over an FTP connection and a page reload is initiate... When arbitrary text is sent over an FTP connection and a page reload is initiated, it is possible to create a modal alert message with this text as the content. This could potentially be used for social engineering attacks. This vulnerability affects Firefox < 66. Scope: local sid: resolved (fixed in 66.0-1)

CVE-2019-17022 [MEDIUM] CVE-2019-17022: firefox - When pasting a &lt;style&gt; tag from the clipboard into a rich text editor, the... When pasting a tag from the clipboard into a rich text editor, the CSS sanitizer does not escape characters. Because the resulting string is pasted directly into the text node of the element this does not result in a direct injection into the webpage; however, if a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would resu

CVE-2019-11762 [MEDIUM] CVE-2019-11762: firefox - If two same-origin documents set document.domain differently to become cross-ori... If two same-origin documents set document.domain differently to become cross-origin, it was possible for them to call arbitrary DOM methods/getters/setters on the now-cross-origin window.

An object tag with a data URI did not correctly inherit the document's Content Security Policy. This allowed a CSP bypass in a cross-origin frame if the document's policy explicitly allowed data: URIs. This vulnerability affects Firefox < 70. Scope: local sid: resolved (fixed in 70.0-1)

CVE-2019-11741 [MEDIUM] CVE-2019-11741: firefox - A compromised sandboxed content process can perform a Universal Cross-site Scrip... A compromised sandboxed content process can perform a Universal Cross-site Scripting (UXSS) attack on content from any site it can cause to be loaded in the same process. Because addons.mozilla.org and accounts.firefox.com have close ties to the Firefox product, malicious manipulation of these sites within the browser can potentially be used to modify a user's Fir

CVE-2019-17001 [MEDIUM] CVE-2019-17001: firefox - A Content-Security-Policy that blocks in-line scripts could be bypassed using an... A Content-Security-Policy that blocks in-line scripts could be bypassed using an object tag to execute JavaScript in the protected document (cross-site scripting). This is a separate bypass from CVE-2019-17000.*Note: This flaw only affected Firefox 69 and was not present in earlier versions.*. This vulnerability affects Firefox < 70.
