CVE-2023-37204 1 Mozilla 1 Firefox 2024-01-07 N/A 6.5 MEDIUM
A website could have obscured the fullscreen notification by using an option element by introducing lag via an expensive computational function. This could have led to user confusion and possible spoofing attacks. This vulnerability affects Firefox < 115.
CVE-2023-34414 1 Mozilla 3 Firefox, Firefox Esr, Thunderbird 2024-01-07 N/A 3.1 LOW
The error page for sites with invalid TLS certificates was missing the activation-delay Firefox uses to protect prompts and permission dialogs from attacks that exploit human response time delays. If a malicious page elicited user clicks in precise locations immediately before navigating to a site with a certificate error and made the renderer extremely busy at the same time, it could create a gap between when the error page was loaded and when the display actually refreshed. With the right timing the elicited clicks could land in that gap and activate the button that overrides the certificate error for that site. This vulnerability affects Firefox ESR < 102.12, Firefox < 114, and Thunderbird < 102.12.
CVE-2023-5731 1 Mozilla 1 Firefox 2024-01-07 N/A 9.8 CRITICAL
Memory safety bugs present in Firefox 118. 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 < 119.
CVE-2023-5722 1 Mozilla 1 Firefox 2024-01-07 N/A 5.3 MEDIUM
Using iterative requests an attacker was able to learn the size of an opaque response, as well as the contents of a server-supplied Vary header. This vulnerability affects Firefox < 119.
CVE-2023-37212 1 Mozilla 1 Firefox 2024-01-07 N/A 8.8 HIGH
Memory safety bugs present in Firefox 114. 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 < 115.
CVE-2023-32208 1 Mozilla 1 Firefox 2024-01-07 N/A 5.3 MEDIUM
Service workers could reveal script base URL due to dynamic `import()`. This vulnerability affects Firefox < 113.
CVE-2023-6135 1 Mozilla 1 Firefox 2024-01-07 N/A 4.3 MEDIUM
Multiple NSS NIST curves were susceptible to a side-channel attack known as "Minerva". This attack could potentially allow an attacker to recover the private key. This vulnerability affects Firefox < 121.
CVE-2023-50762 2 Debian, Mozilla 2 Debian Linux, Thunderbird 2023-12-29 N/A 4.3 MEDIUM
When processing a PGP/MIME payload that contains digitally signed text, the first paragraph of the text was never shown to the user. This is because the text was interpreted as a MIME message and the first paragraph was always treated as an email header section. A digitally signed text from a different context, such as a signed GIT commit, could be used to spoof an email message. This vulnerability affects Thunderbird < 115.6.
CVE-2023-50761 2 Debian, Mozilla 2 Debian Linux, Thunderbird 2023-12-29 N/A 4.3 MEDIUM
The signature of a digitally signed S/MIME email message may optionally specify the signature creation date and time. If present, Thunderbird did not compare the signature creation date with the message date and time, and displayed a valid signature despite a date or time mismatch. This could be used to give recipients the impression that a message was sent at a different date or time. This vulnerability affects Thunderbird < 115.6.
CVE-2006-6499 3 Canonical, Debian, Mozilla 5 Ubuntu Linux, Debian Linux, Firefox and 2 more 2023-12-22 4.3 MEDIUM N/A
The js_dtoa function in Mozilla Firefox 2.x before 2.0.0.1, 1.5.x before 1.5.0.9, Thunderbird before 1.5.0.9, and SeaMonkey before 1.0.7 overwrites memory instead of exiting when the floating point precision is reduced, which allows remote attackers to cause a denial of service via any plugins that reduce the precision.
CVE-2023-4421 1 Mozilla 1 Nss 2023-12-20 N/A 6.5 MEDIUM
The NSS code used for checking PKCS#1 v1.5 was leaking information useful in mounting Bleichenbacher-like attacks. Both the overall correctness of the padding as well as the length of the encrypted message was leaking through timing side-channel. By sending large number of attacker-selected ciphertexts, the attacker would be able to decrypt a previously intercepted PKCS#1 v1.5 ciphertext (for example, to decrypt a TLS session that used RSA key exchange), or forge a signature using the victim's key. The issue was fixed by implementing the implicit rejection algorithm, in which the NSS returns a deterministic random message in case invalid padding is detected, as proposed in the Marvin Attack paper. This vulnerability affects NSS < 3.61.
CVE-2023-6208 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-11-30 N/A 8.8 HIGH
When using X11, text selected by the page using the Selection API was erroneously copied into the primary selection, a temporary storage not unlike the clipboard. *This bug only affects Firefox on X11. Other systems are unaffected.* This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
CVE-2023-6204 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-11-30 N/A 6.5 MEDIUM
On some systems—depending on the graphics settings and drivers—it was possible to force an out-of-bounds read and leak memory data into the images created on the canvas element. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
CVE-2023-6205 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-11-30 N/A 6.5 MEDIUM
It was possible to cause the use of a MessagePort after it had already been freed, which could potentially have led to an exploitable crash. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
CVE-2023-6209 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-11-30 N/A 6.5 MEDIUM
Relative URLs starting with three slashes were incorrectly parsed, and a path-traversal "/../" part in the path could be used to override the specified host. This could contribute to security problems in web sites. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
CVE-2023-6207 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-11-30 N/A 8.8 HIGH
Ownership mismanagement led to a use-after-free in ReadableByteStreams This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
CVE-2023-6206 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-11-30 N/A 5.4 MEDIUM
The black fade animation when exiting fullscreen is roughly the length of the anti-clickjacking delay on permission prompts. It was possible to use this fact to surprise users by luring them to click where the permission grant button would be about to appear. This vulnerability affects Firefox < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
CVE-2023-6212 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-11-30 N/A 8.8 HIGH
Memory safety bugs present in Firefox 119, Firefox ESR 115.4, and Thunderbird 115.4. 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 < 120, Firefox ESR < 115.5.0, and Thunderbird < 115.5.
CVE-2023-49060 1 Mozilla 1 Firefox 2023-11-30 N/A 9.8 CRITICAL
An attacker could have accessed internal pages or data by ex-filtrating a security key from ReaderMode via the `referrerpolicy` attribute. This vulnerability affects Firefox for iOS < 120.
CVE-2023-49061 1 Mozilla 1 Firefox 2023-11-28 N/A 6.1 MEDIUM
An attacker could have performed HTML template injection via Reader Mode and exfiltrated user information. This vulnerability affects Firefox for iOS < 120.
