CVE-2020-15658 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-11-21 6.5 Medium
The code for downloading files did not properly take care of special characters, which led to an attacker being able to cut off the file ending at an earlier position, leading to a different file type being downloaded than shown in the dialog. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15657 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-11-21 7.8 High
Firefox could be made to load attacker-supplied DLL files from the installation directory. This required an attacker that is already capable of placing files in the installation directory. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15656 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-11-21 8.8 High
JIT optimizations involving the Javascript arguments object could confuse later optimizations. This risk was already mitigated by various precautions in the code, resulting in this bug rated at only moderate severity. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15655 3 Canonical, Mozilla, Opensuse 5 Ubuntu Linux, Firefox, Firefox Esr and 2 more 2024-11-21 6.5 Medium

CVE-2020-15654 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-11-21 6.5 Medium
When in an endless loop, a website specifying a custom cursor using CSS could make it look like the user is interacting with the user interface, when they are not. This could lead to a perceived broken state, especially when interactions with existing browser dialogs and warnings do not work. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15653 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-11-21 6.5 Medium
An iframe sandbox element with the allow-popups flag could be bypassed when using noopener links. This could have led to security issues for websites relying on sandbox configurations that allowed popups and hosted arbitrary content. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
CVE-2020-15652 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-11-21 6.5 Medium
By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a cross-origin redirect. This applied only to content that can be parsed as script. This vulnerability affects Firefox < 79, Firefox ESR < 68.11, Firefox ESR < 78.1, Thunderbird < 68.11, and Thunderbird < 78.1.
CVE-2020-15648 2 Mozilla, Redhat 5 Firefox, Thunderbird, Enterprise Linux and 2 more 2024-11-21 6.5 Medium
Using object or embed tags, it was possible to frame other websites, even if they disallowed framing using the X-Frame-Options header. This vulnerability affects Thunderbird < 78 and Firefox < 78.0.2.
CVE-2020-15646 2 Mozilla, Redhat 4 Thunderbird, Enterprise Linux, Rhel E4s and 1 more 2024-11-21 5.9 Medium
If an attacker intercepts Thunderbird's initial attempt to perform automatic account setup using the Microsoft Exchange autodiscovery mechanism, and the attacker sends a crafted response, then Thunderbird sends username and password over https to a server controlled by the attacker. This vulnerability affects Thunderbird < 68.10.0.
CVE-2020-12421 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-11-21 6.5 Medium
When performing add-on updates, certificate chains terminating in non-built-in-roots were rejected (even if they were legitimately added by an administrator.) This could have caused add-ons to become out-of-date silently without notification to the user. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12420 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-11-21 8.8 High
When trying to connect to a STUN server, a race condition could have caused a use-after-free of a pointer, leading to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12419 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-11-21 8.8 High
When processing callbacks that occurred during window flushing in the parent process, the associated window may die; causing a use-after-free condition. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12418 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-11-21 6.5 Medium
Manipulating individual parts of a URL object could have caused an out-of-bounds read, leaking process memory to malicious JavaScript. This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12417 4 Canonical, Mozilla, Opensuse and 1 more 8 Ubuntu Linux, Firefox, Firefox Esr and 5 more 2024-11-21 8.8 High
Due to confusion about ValueTags on JavaScript Objects, an object may pass through the type barrier, resulting in memory corruption and a potentially exploitable crash. *Note: this issue only affects Firefox on ARM64 platforms.* This vulnerability affects Firefox ESR < 68.10, Firefox < 78, and Thunderbird < 68.10.0.
CVE-2020-12406 3 Canonical, Mozilla, Redhat 7 Ubuntu Linux, Firefox, Firefox Esr and 4 more 2024-11-21 8.8 High
Mozilla Developer Iain Ireland discovered a missing type check during unboxed objects removal, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.
