A buffer overflow can occur when rendering canvas content while adjusting the height and width of the element dynamically, causing data to be written outside of the currently computed boundaries. This results in a potentially exploitable crash.
A use-after-free vulnerability can occur when deleting an input element during a mutation event handler triggered by focusing that element. This results in a potentially exploitable crash.
Decrypted S/MIME parts, when included in HTML crafted for an attack, can leak plaintext when included in a a HTML reply/forward.
dDecrypted S/MIME parts hidden with CSS or can leak plaintext when included in a HTML reply/forward.
An integer overflow can occur during graphics operations done by the Supplemental Streaming SIMD Extensions 3 (SSSE3) scaler, resulting in a potentially exploitable crash.
A use-after-free vulnerability can occur when script uses mutation events to move DOM nodes between documents, resulting in the old document that held the node being freed but the node still having a pointer referencing it. This results in a potentially exploitable crash.
NPAPI plugins, such as Adobe Flash, can send non-simple cross-origin requests, bypassing CORS by making a same-origin POST that does a 307 redirect to the target site. This allows for a malicious site to engage in cross-site request forgery (CSRF) attacks.
A compromised IPC child process can escape the content sandbox and list the names of arbitrary files on the file system without user consent or interaction. This could result in exposure of private local files.
An invalid grid size during QCMS (color profile) transformations can result in the out-of-bounds read interpreted as a float value. This could leak private data into the output.
Windows 10 does not warn users before opening executable files with the SettingContent-ms extension even when they have been downloaded from the internet and have the “Mark of the Web.” Without the warning, unsuspecting users unfamiliar with this new file type might run an unwanted executable. This also allows a WebExtension with the limited downloads.open permission to execute arbitrary code without user interaction on Windows 10 systems Note: this issue only affects Windows operating systems. Other operating systems are unaffected.
Plaintext of decrypted emails can leak through by user submitting an embedded form by pressing enter key within a text input field.
Mozilla developers and community members Alex Gaynor, Christoph Diehl, Christian Holler, Jason Kratzer, David Major, Jon Coppeard, Nicolas B. Pierron, Jason Kratzer, Marcia Knous, and Ronald Crane reported memory safety bugs present in Firefox 60, Firefox ESR 60, Firefox ESR 52.8, and Thunderbird 52.8. 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.
