From https://www.openwall.com/lists/oss-security/2021/08/30/1:

Security vulnerabilities were identified in the open source NTFS-3G and NTFSPROGS software. These vulnerabilities were confirmed and resolved. To our knowledge, these vulnerabilities have not been exploited.

These vulnerabilities may allow an attacker using a maliciously crafted NTFS-formatted image file or external storage to potentially execute arbitrary privileged code, if the attacker has either local access and the ntfs-3g binary is setuid root, or if the attacker has physical access to an external port to a computer which is configured to run the ntfs-3g binary or one of the ntfsprogs tools when the external storage is plugged into the computer. These vulnerabilities result from incorrect validation of some of the NTFS metadata that could potentially cause buffer overflows, which could be exploited by an attacker. Common ways for attackers to gain physical access to a machine is through social engineering or an evil maid attack on an unattended computer.

We recommend installing and applying the update with the security fixes, and advise to follow security guidance and frameworks such as NIST for assessing and improving an organization’s abilities to prevent, detect, and respond to security threats and cyber attacks.

AFFECTED PRODUCTS: All previous versions of open source NTFS-3G and NTFSPROGS.

WORKAROUND: None

SOLUTION: Upgrade to 2021.8.22

ACKNOWLEDGMENT: Jeremy Galindo, Akshay Ajayan, Kyle Zeng and Fish Wang for reporting these vulnerabilities.

Use-after-free while manipulating XSL in XSLT documents

A potential use-after-free found through fuzzing during DOM manipulation of SVG content.

The JSON viewer in the Developer Tools uses insecure methods to create a communication channel for copying and viewing JSON or HTTP headers data, allowing for potential privilege escalation.

Hashed codes of JavaScript objects are shared between pages. This allows for pointer leaks because an object's address can be discovered through hash codes, and also allows for data leakage of an object's content using these hash codes. This vulnerability affects Thunderbird < 45.7, Firefox ESR < 45.7, and Firefox < 51.

A use-after-free vulnerability in the Media Decoder when working with media files when some events are fired after the media elements are freed from memory.

URLs containing certain unicode glyphs for alternative hyphens and quotes do not properly trigger punycode display, allowing for domain name spoofing attacks in the location bar.

WebExtension scripts can use the "data:" protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions. This vulnerability affects Firefox ESR < 45.7 and Firefox < 51.

Use-after-free while manipulating DOM events and removing audio elements due to errors in the handling of node adoption.

Event handlers on "marquee" elements were executed despite a strict Content Security Policy (CSP) that disallowed inline JavaScript. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.

Use-after-free resulting in potentially exploitable crash when manipulating DOM subtrees in the Editor.

External resources that should be blocked when loaded by SVG images can bypass security restrictions through the use of "data:" URLs. This could allow for cross-domain data leakage. This vulnerability affects Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.

Memory safety bugs were reported in Thunderbird 45.5. 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 Firefox < 50.1, Firefox ESR < 45.6, and Thunderbird < 45.6.

A use-after-free vulnerability when using an incorrect URL during the reloading of a docshell. This results in a potentially exploitable crash.

A use-after-free vulnerability with content viewer listeners that results in a potentially exploitable crash.

A use-after-free vulnerability during video control operations when a "<track>" element holds a reference to an older window if that window has been replaced in the DOM. This results in a potentially exploitable crash. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.

A use-after-free vulnerability during specific user interactions with the input method editor (IME) in some languages due to how events are handled. This results in a potentially exploitable crash but would require specific user interaction to trigger.

An out-of-bounds read in WebGL with a maliciously crafted "ImageInfo" object during WebGL operations. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.

A use-after-free vulnerability can occur in the Fetch API when the worker or the associated window are freed when still in use, resulting in a potentially exploitable crash.

A use-after-free vulnerability can occur during WebRTC connections when interacting with the DTMF timers. This results in a potentially exploitable crash.

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 < 55.

The Developer Tools feature suffered from 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.
