Summary
Multiple security issues were discovered in Firefox. If a user were
tricked into opening a specially crafted website, an attacker could
potentially exploit these to cause a denial of service, obtain sensitive
information across domains, or execute arbitrary code. (CVE-2024-6601,
CVE-2024-6604, CVE-2024-6607, CVE-2024-6608, CVE-2024-6610, CVE-2024-6611,
CVE-2024-6612, CVE-2024-6613, CVE-2024-6614, CVE-2024-6615)
It was discovered that Firefox did not properly manage certain memory
operations in the NSS. An attacker could potentially exploit this issue to
cause a denial of service, or execute arbitrary code. (CVE-2024-6602,
CVE-2024-6609)
Irvan Kurniawan discovered that Firefox did not properly manage memory
during thread creation. An attacker could potentially exploit this
issue to cause a denial of service, or execute arbitrary code.
(CVE-2024-6603)
It was discovered that Firefox incorrectly handled array accesses in the
clipboard component, leading to an out-of-bounds read vulnerability. An
attacker could possibly use this issue to cause a denial of service or
expose sensitive information. (CVE-2024-6606)

Vulnerabilities 14
-
Critical 9.8
Memory corruption in NSS
A mismatch between allocator and deallocator could have led to memory corruption. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.
-
Critical 9.8
Incorrect handling of SameSite cookies
A nested iframe, triggering a cross-site navigation, could send SameSite=Strict or Lax cookies. This vulnerability affects Firefox < 128 and Thunderbird < 128.
-
High 8.8
Leaving pointerlock by pressing the escape key could be prevented
It was possible to prevent a user from exiting pointerlock when pressing escape and to overlay customValidity notifications from a `<select>` element over certain permission prompts. This could be used to confuse a user into giving a site unintended per…
-
High 8.8
Memory corruption in NSS
When almost out-of-memory an elliptic curve key which was never allocated could have been freed again. This vulnerability affects Firefox < 128 and Thunderbird < 128.
-
High 8.8
Memory safety bugs fixed in Firefox 128 and Thunderbird 128
Memory safety bugs present in Firefox 127 and Thunderbird 127. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 1…
-
High 8.2
Out-of-bounds read in clipboard component
Clipboard code failed to check the index on an array access. This could have led to an out-of-bounds read. This vulnerability affects Firefox < 128 and Thunderbird < 128.
-
High 7.5
Memory safety bugs fixed in Firefox 128, Firefox ESR 115.13, Thunderbird 128, and Thunderbird 115.13
Memory safety bugs present in Firefox 127, Firefox ESR 115.12, and Thunderbird 115.12. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerabi…
-
High 7.4
Memory corruption in thread creation
In an out-of-memory scenario an allocation could fail but free would have been called on the pointer afterwards leading to memory corruption. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.
-
Medium 6.3
Form validation popups could block exiting full-screen mode
Form validation popups could capture escape key presses. Therefore, spamming form validation messages could be used to prevent users from exiting full-screen mode. This vulnerability affects Firefox < 128 and Thunderbird < 128.
-
Medium 5.5
Incorrect listing of stack frames
The frame iterator could get stuck in a loop when encountering certain wasm frames leading to incorrect stack traces. This vulnerability affects Firefox < 128 and Thunderbird < 128.
-
Medium 5.3
CSP violation leakage when using devtools
CSP violations generated links in the console tab of the developer tools, pointing to the violating resource. This caused a DNS prefetch which leaked that a CSP violation happened. This vulnerability affects Firefox < 128 and Thunderbird < 128.
-
Medium 4.7
Race condition in permission assignment
A race condition could lead to a cross-origin container obtaining permissions of the top-level origin. This vulnerability affects Firefox < 128, Firefox ESR < 115.13, Thunderbird < 115.13, and Thunderbird < 128.
-
Medium 4.3
Cursor could be moved out of the viewport using pointerlock.
It was possible to move the cursor using pointerlock from an iframe. This allowed moving the cursor outside of the viewport and the Firefox window. This vulnerability affects Firefox < 128 and Thunderbird < 128.
-
Medium 4.3
Incorrect listing of stack frames
The frame iterator could get stuck in a loop when encountering certain wasm frames leading to incorrect stack traces. This vulnerability affects Firefox < 128 and Thunderbird < 128.
