SUSE CVE-2017-7784

A use-after-free vulnerability can occur when reading an image observer during frame reconstruction after the observer has been freed. This results in a potentially exploitable crash. This vulnerability affects Thunderbird 52.3, Firefox ESR 52.3, and Firefox 55...

CVE-2017-7811

Memory safety bugs were reported in Firefox 55. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox 56...

CVE-2017-7810

Memory safety bugs were reported in Firefox 55 and Firefox ESR 52.3. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox 56, Firefox ESR 52.4, and Thunderbird...

CVE-2017-7797

Response header name interning does not have same-origin protections and these headers are stored in a global registry. This allows stored header names to be available cross-origin. This vulnerability affects Firefox 55...

DEBIAN-CVE-2017-7786

A buffer overflow can occur when the image renderer attempts to paint non-displayable SVG elements. This results in a potentially exploitable crash. This vulnerability affects Thunderbird 52.3, Firefox ESR 52.3, and Firefox 55...

CVE-2017-7783

If a long user name is used in a username/password combination in a site URL such as " http://UserName:[email protected]", the resulting modal prompt will hang in a non-responsive state or crash, causing a denial of service. This vulnerability affects Firefox 55...

Design/Logic Flaw

The Developer Tools feature suffers from a XUL injection vulnerability due to improper sanitization of the web page source code. In the worst case, this could allow arbitrary code execution when opening a malicious page with the style editor tool. This vulnerability affects Firefox ESR 52.3 and...

Design/Logic Flaw

On Windows systems, the logger run by the Windows updater deletes the file "update.log" before it runs in order to write a new log of that name. The path to this file is supplied at the command line to the updater and could be used in concert with another local exploit to delete a different file...

Code injection

An error occurs in the elliptic curve point addition algorithm that uses mixed Jacobian-affine coordinates where it can yield a result "POINTATINFINITY" when it should not. A man-in-the-middle attacker could use this to interfere with a connection, resulting in an attacked party computing an...

CVE-2017-7796

On Windows systems, the logger run by the Windows updater deletes the file "update.log" before it runs in order to write a new log of that name. The path to this file is supplied at the command line to the updater and could be used in concert with another local exploit to delete a different file...

Path traversal

A content security policy CSP "frame-ancestors" directive containing origins with paths allows for comparisons against those paths instead of the origin. This results in a cross-origin information leak of this path information. This vulnerability affects Firefox 55...

On Windows systems, the logger run by the Windows updater deletes the file "update.log" before it runs in order to write a new log of that name. The path to this file is supplied at the command line to the updater and could be used in concert with another local exploit to delete a different file...

CVE-2017-7789

If a server sends two Strict-Transport-Security STS headers for a single connection, they will be rejected as invalid and HTTP Strict Transport Security HSTS will not be enabled for the connection. This vulnerability affects Firefox 55...

CVE-2017-7799

JavaScript in the "about:webrtc" page is not sanitized properly being assigned to "innerHTML". Data on this page is supplied by WebRTC usage and is not under third-party control, making this difficult to exploit, but the vulnerability could possibly be used for a cross-site scripting XSS attack...

CVE-2017-7781

CVE-2017-7781 affects Firefox before 55 due to an error in the elliptic-curve point addition using mixed Jacobian–affine coordinates, which can yield a spuriously computed POINT_AT_INFINITY. This could let a man‑in‑the‑middle attacker interfere with a connection and cause the affected party to co...

CVE-2017-7811

Memory safety bugs were reported in Firefox 55. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. This vulnerability affects Firefox 56...

Mozilla: Use-after-free with marquee during window resizing

A use-after-free vulnerability can occur while re-computing layout for a "marquee" element during window resizing where the updated style object is freed while still in use. This results in a potentially exploitable crash. This vulnerability affects Thunderbird 52.3, Firefox ESR 52.3, and Firefox...

CVE-2017-7788

When an "iframe" has a "sandbox" attribute and its content is specified using "srcdoc", that content does not inherit the containing page's Content Security Policy CSP as it should unless the sandbox attribute included "allow-same-origin". This vulnerability affects Firefox 55...

UBUNTU-CVE-2017-7753

An out-of-bounds read occurs when applying style rules to pseudo-elements, such as ::first-line, using cached style data. This vulnerability affects Thunderbird 52.3, Firefox ESR 52.3, and Firefox 55...

UBUNTU-CVE-2017-7791

On pages containing an iframe, the "data:" protocol can be used to create a modal alert that will render over arbitrary domains following page navigation, spoofing of the origin of the modal alert from the iframe content. This vulnerability affects Thunderbird 52.3, Firefox ESR 52.3, and Firefox ...
