CVE-2018-18506 5 Canonical, Debian, Mozilla and 2 more 12 Ubuntu Linux, Debian Linux, Firefox and 9 more 2023-03-17 4.3 MEDIUM 5.9 MEDIUM
When proxy auto-detection is enabled, if a web server serves a Proxy Auto-Configuration (PAC) file or if a PAC file is loaded locally, this PAC file can specify that requests to the localhost are to be sent through the proxy to another server. This behavior is disallowed by default when a proxy is manually configured, but when enabled could allow for attacks on services and tools that bind to the localhost for networked behavior if they are accessed through browsing. This vulnerability affects Firefox < 65.
CVE-2019-11721 2 Mozilla, Opensuse 2 Firefox, Leap 2023-03-02 4.3 MEDIUM 6.5 MEDIUM
The unicode latin 'kra' character can be used to spoof a standard 'k' character in the addressbar. This allows for domain spoofing attacks as do not display as punycode text, allowing for user confusion. This vulnerability affects Firefox < 68.
CVE-2019-11720 2 Mozilla, Opensuse 2 Firefox, Leap 2023-03-02 4.3 MEDIUM 6.1 MEDIUM
Some unicode characters are incorrectly treated as whitespace during the parsing of web content instead of triggering parsing errors. This allows malicious code to then be processed, evading cross-site scripting (XSS) filtering. This vulnerability affects Firefox < 68.
CVE-2019-11711 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2023-03-01 6.8 MEDIUM 8.8 HIGH
When an inner window is reused, it does not consider the use of document.domain for cross-origin protections. If pages on different subdomains ever cooperatively use document.domain, then either page can abuse this to inject script into arbitrary pages on the other subdomain, even those that did not use document.domain to relax their origin security. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2020-12413 1 Mozilla 2 Firefox, Firefox Esr 2023-02-28 N/A 5.9 MEDIUM
The Raccoon attack is a timing attack on DHE ciphersuites inherit in the TLS specification. To mitigate this vulnerability, Firefox disabled support for DHE ciphersuites.
CVE-2020-12388 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2023-02-28 7.5 HIGH 10.0 CRITICAL
The Firefox content processes did not sufficiently lockdown access control which could result in a sandbox escape. *Note: this issue only affects Firefox on Windows operating systems.*. This vulnerability affects Firefox ESR < 68.8 and Firefox < 76.
CVE-2020-12397 2 Canonical, Mozilla 2 Ubuntu Linux, Thunderbird 2023-02-28 4.3 MEDIUM 4.3 MEDIUM
By encoding Unicode whitespace characters within the From email header, an attacker can spoof the sender email address that Thunderbird displays. This vulnerability affects Thunderbird < 68.8.0.
CVE-2020-6817 1 Mozilla 1 Bleach 2023-02-28 N/A 7.5 HIGH
bleach.clean behavior parsing style attributes could result in a regular expression denial of service (ReDoS). Calls to bleach.clean with an allowed tag with an allowed style attribute are vulnerable to ReDoS. For example, bleach.clean(..., attributes={'a': ['style']}).
CVE-2019-9811 4 Debian, Mozilla, Novell and 1 more 6 Debian Linux, Firefox, Firefox Esr and 3 more 2023-02-28 5.1 MEDIUM 8.3 HIGH
As part of a winning Pwn2Own entry, a researcher demonstrated a sandbox escape by installing a malicious language pack and then opening a browser feature that used the compromised translation. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2019-11717 4 Debian, Mozilla, Novell and 1 more 6 Debian Linux, Firefox, Firefox Esr and 3 more 2023-02-28 5.0 MEDIUM 5.3 MEDIUM
A vulnerability exists where the caret ("^") character is improperly escaped constructing some URIs due to it being used as a separator, allowing for possible spoofing of origin attributes. This vulnerability affects Firefox ESR < 60.8, Firefox < 68, and Thunderbird < 60.8.
CVE-2022-0637 1 Mozilla 1 Pollbot 2023-02-28 N/A 6.1 MEDIUM
There was an open redirection vulnerability pollbot, which was used in and An attacker could have redirected anyone to malicious sites.
CVE-2021-43529 1 Mozilla 1 Thunderbird 2023-02-28 N/A 9.8 CRITICAL
Thunderbird versions prior to 91.3.0 are vulnerable to the heap overflow described in CVE-2021-43527 when processing S/MIME messages. Thunderbird versions 91.3.0 and later will not call the vulnerable code when processing S/MIME messages that contain certificates with DER-encoded DSA or RSA-PSS signatures.
CVE-2019-17003 1 Mozilla 1 Firefox 2023-02-27 N/A 6.1 MEDIUM
Scanning a QR code that contained a javascript: URL would have resulted in the Javascript being executed.
CVE-2021-23980 1 Mozilla 1 Bleach 2023-02-27 N/A 6.1 MEDIUM
A mutation XSS affects users calling bleach.clean with all of: svg or math in the allowed tags p or br in allowed tags style, title, noscript, script, textarea, noframes, iframe, or xmp in allowed tags the keyword argument strip_comments=False Note: none of the above tags are in the default allowed tags and strip_comments defaults to True.
CVE-2020-6812 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2023-02-22 5.0 MEDIUM 5.3 MEDIUM
The first time AirPods are connected to an iPhone, they become named after the user's name by default (e.g. Jane Doe's AirPods.) Websites with camera or microphone permission are able to enumerate device names, disclosing the user's name. To resolve this issue, Firefox added a special case that renames devices containing the substring 'AirPods' to simply 'AirPods'. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
CVE-2021-43527 4 Mozilla, Netapp, Oracle and 1 more 10 Nss, Nss Esr, Cloud Backup and 7 more 2023-02-22 7.5 HIGH 9.8 CRITICAL
NSS (Network Security Services) versions prior to 3.73 or 3.68.1 ESR are vulnerable to a heap overflow when handling DER-encoded DSA or RSA-PSS signatures. Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS \#7, or PKCS \#12 are likely to be impacted. Applications using NSS for certificate validation or other TLS, X.509, OCSP or CRL functionality may be impacted, depending on how they configure NSS. *Note: This vulnerability does NOT impact Mozilla Firefox.* However, email clients and PDF viewers that use NSS for signature verification, such as Thunderbird, LibreOffice, Evolution and Evince are believed to be impacted. This vulnerability affects NSS < 3.73 and NSS < 3.68.1.
CVE-2020-12401 1 Mozilla 1 Firefox 2023-02-20 1.9 LOW 4.7 MEDIUM
During ECDSA signature generation, padding applied in the nonce designed to ensure constant-time scalar multiplication was removed, resulting in variable-time execution dependent on secret data. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-6829 1 Mozilla 1 Firefox 2023-02-20 5.0 MEDIUM 5.3 MEDIUM
When performing EC scalar point multiplication, the wNAF point multiplication algorithm was used; which leaked partial information about the nonce used during signature generation. Given an electro-magnetic trace of a few signature generations, the private key could have been computed. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
CVE-2020-12403 1 Mozilla 1 Nss 2023-02-20 6.4 MEDIUM 9.1 CRITICAL
A flaw was found in the way CHACHA20-POLY1305 was implemented in NSS in versions before 3.55. When using multi-part Chacha20, it could cause out-of-bounds reads. This issue was fixed by explicitly disabling multi-part ChaCha20 (which was not functioning correctly) and strictly enforcing tag length. The highest threat from this vulnerability is to confidentiality and system availability.
CVE-2020-12400 1 Mozilla 1 Firefox 2023-02-20 1.2 LOW 4.7 MEDIUM
When converting coordinates from projective to affine, the modular inversion was not performed in constant time, resulting in a possible timing-based side channel attack. This vulnerability affects Firefox < 80 and Firefox for Android < 80.
