Buffer overflow

A buffer overflow in WebGL triggerable by web content, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird 52.1, Firefox ESR 45.9, Firefox ESR 52.1, and Firefox 53...

Code injection

An error in the "WindowsDllDetourPatcher" where a RWX "Read/Write/Execute" 4k block is allocated but never protected, violating DEP protections. Note: This attack only affects Windows operating systems. Other operating systems are not affected. This vulnerability affects Thunderbird 52.3, Firefox...

Code injection

When a page's content security policy CSP header contains a "sandbox" directive, other directives are ignored. This results in the incorrect enforcement of CSP. This vulnerability affects Thunderbird 52.3, Firefox ESR 52.3, and 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

A mechanism that uses AppCache to hijack a URL in a domain using fallback by serving the files from a sub-path on the domain. This has been addressed by requiring fallback files be inside the manifest directory. This vulnerability affects Thunderbird 52.3, Firefox ESR 52.3, and Firefox 55...

Buffer overflow

A buffer overflow can occur when manipulating the SVG "animatedPathSegList" through script. This results in a potentially exploitable crash. This vulnerability affects Thunderbird 52.7, Firefox ESR 52.7, and Firefox 59...

Design/Logic Flaw

A use-after-free vulnerability can occur in the compositor during certain graphics operations when a raw pointer is used instead of a reference counted one. This results in a potentially exploitable crash. This vulnerability affects Firefox ESR 52.7.3 and Firefox 59.0.2...

Memory corruption

A lack of parameter validation on IPC messages results in a potential out-of-bounds write through malformed IPC messages. This can potentially allow for sandbox escape through memory corruption in the parent process. This vulnerability affects Thunderbird 52.7, Firefox ESR 52.7, and Firefox 59...

Design/Logic Flaw

A use-after-free vulnerability can occur during XSL transformations when the source document for the transformation is manipulated by script content during the transformation. This results in a potentially exploitable crash. This vulnerability affects Thunderbird 52.6, Firefox ESR 52.6, and Firef...

Integer overflow

An integer overflow vulnerability in the Skia library when allocating memory for edge builders on some systems with at least 8 GB of RAM. This results in the use of uninitialized memory, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird 52.6, Firefox ESR 52.6, a...

A use-after-free vulnerability can occur while editing events in form elements on a page, resulting in a potentially exploitable crash. This vulnerability affects Firefox ESR 52.6 and Thunderbird 52.6...

Design/Logic Flaw

The Mozilla Updater can be made to choose an arbitrary target working directory for output files resulting from the update process. This vulnerability requires local system access. Note: this issue only affects Windows operating systems. This vulnerability affects Thunderbird 45.5, Firefox ESR...

Memory corruption

Memory safety bugs were reported in Firefox 57 and Firefox ESR 52.5. 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 Thunderbird 52.6, Firefox ESR 52.6, and Firef...

Buffer overflow

A buffer overflow vulnerability while parsing "application/http-index-format" format content when the header contains improperly formatted data. This allows for an out-of-bounds read of data from memory. This vulnerability affects Thunderbird 52.1, Firefox ESR 45.9, Firefox ESR 52.1, and Firefox ...

CVE-2017-7804

The destructor function for the "WindowsDllDetourPatcher" class can be re-purposed by malicious code in concert with another vulnerability to write arbitrary data to an attacker controlled location in memory. This can be used to bypass existing memory protections in this situation. Note: This...

CVE-2016-5293

When the Mozilla Updater is run, if the Updater's log file in the working directory points to a hardlink, data can be appended to an arbitrary local file. This vulnerability requires local system access. Note: this issue only affects Windows operating systems. This vulnerability affects Firefox E...
