CVE-2019-17009 3 Microsoft, Mozilla, Opensuse 5 Windows, Firefox, Firefox Esr and 2 more 2024-11-21 7.8 High
When running, the updater service wrote status and log files to an unrestricted location; potentially allowing an unprivileged process to locate and exploit a vulnerability in file handling in the updater service. *Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.*. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
CVE-2019-17008 3 Mozilla, Opensuse, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
When using nested workers, a use-after-free could occur during worker destruction. This resulted in a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
CVE-2019-17005 4 Canonical, Mozilla, Opensuse and 1 more 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-11-21 8.8 High
The plain text serializer used a fixed-size array for the number of <ol> elements it could process; however it was possible to overflow the static-sized array leading to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.3, Firefox ESR < 68.3, and Firefox < 71.
CVE-2019-17003 1 Mozilla 1 Firefox 2024-11-21 6.1 Medium
Scanning a QR code that contained a javascript: URL would have resulted in the Javascript being executed.
CVE-2019-17002 1 Mozilla 1 Firefox 2024-11-21 4.3 Medium
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. This vulnerability affects Firefox < 70.
CVE-2019-17001 1 Mozilla 1 Firefox 2024-11-21 6.1 Medium
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.
CVE-2019-17000 1 Mozilla 1 Firefox 2024-11-21 6.1 Medium
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.
CVE-2019-14953 2 Jetbrains, Mozilla 2 Youtrack, Firefox 2024-11-21 6.1 Medium
JetBrains YouTrack versions before 2019.2.53938 had a possible XSS through issue attachments when using the Firefox browser.
CVE-2019-11765 1 Mozilla 1 Firefox 2024-11-21 6.5 Medium
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 Firefox < 70.
CVE-2019-11764 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 8.8 High
Mozilla developers and community members reported memory safety bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11763 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 6.1 Medium
Failure to correctly handle null bytes when processing HTML entities resulted in Firefox incorrectly parsing these entities. This could have led to HTML comment text being treated as HTML which could have led to XSS in a web application under certain conditions. It could have also led to HTML entities being masked from filters - enabling the use of entities to mask the actual characters of interest from filters. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11762 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 6.1 Medium
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. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11761 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 5.4 Medium
By using a form with a data URI it was possible to gain access to the privileged JSONView object that had been cloned into content. Impact from exposing this object appears to be minimal, however it was a bypass of existing defense in depth mechanisms. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11760 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 8.8 High
A fixed-size stack buffer could overflow in nrappkit when doing WebRTC signaling. This resulted in a potentially exploitable crash in some instances. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11759 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 8.8 High
An attacker could have caused 4 bytes of HMAC output to be written past the end of a buffer stored on the stack. This could be used by an attacker to execute arbitrary code or more likely lead to a crash. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11758 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 8.8 High
Mozilla community member Philipp reported a memory safety bug present in Firefox 68 when 360 Total Security was installed. This bug showed evidence of memory corruption in the accessibility engine and we presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Firefox < 69, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11757 3 Canonical, Mozilla, Redhat 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 8.8 High
When following the value's prototype chain, it was possible to retain a reference to a locale, delete it, and subsequently reference it. This resulted in a use-after-free and a potentially exploitable crash. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-11756 2 Mozilla, Redhat 7 Firefox, Enterprise Linux, Openshift Do and 4 more 2024-11-21 8.8 High
Improper refcounting of soft token session objects could cause a use-after-free and crash (likely limited to a denial of service). This vulnerability affects Firefox < 71.
CVE-2019-11754 1 Mozilla 1 Firefox 2024-11-21 4.3 Medium
When the pointer lock is enabled by a website though requestPointerLock(), no user notification is given. This could allow a malicious website to hijack the mouse pointer and confuse users. This vulnerability affects Firefox < 69.0.1.
CVE-2019-11753 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2024-11-21 7.8 High
The Firefox installer allows Firefox to be installed to a custom user writable location, leaving it unprotected from manipulation by unprivileged users or malware. If the Mozilla Maintenance Service is manipulated to update this unprotected location and the updated maintenance service in the unprotected location has been altered, the altered maintenance service can run with elevated privileges during the update process due to a lack of integrity checks. This allows for privilege escalation if the executable has been replaced locally. <br>*Note: This attack requires local system access and only affects Windows. Other operating systems are not affected.*. This vulnerability affects Firefox < 69, Firefox ESR < 60.9, and Firefox ESR < 68.1.
