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-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-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-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-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-2020-12400 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.
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-2022-46871 2 Debian, Mozilla 2 Debian Linux, Firefox 2023-02-20 N/A 8.8 HIGH
An out of date library (libusrsctp) contained vulnerabilities that could potentially be exploited. This vulnerability affects Firefox < 108.
CVE-2022-46877 2 Debian, Mozilla 2 Debian Linux, Firefox 2023-02-20 N/A 4.3 MEDIUM
By confusing the browser, the fullscreen notification could have been delayed or suppressed, resulting in potential user confusion or spoofing attacks. This vulnerability affects Firefox < 108.
CVE-2009-2409 3 Gnu, Mozilla, Openssl 4 Gnutls, Firefox, Nss and 1 more 2023-02-12 5.1 MEDIUM N/A
The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time. NOTE: the scope of this issue is currently limited because the amount of computation required is still large.
CVE-2009-1308 1 Mozilla 3 Firefox, Seamonkey, Thunderbird 2023-02-12 4.3 MEDIUM N/A
Cross-site scripting (XSS) vulnerability in Mozilla Firefox before 3.0.9, Thunderbird, and SeaMonkey allows remote attackers to inject arbitrary web script or HTML via vectors involving XBL JavaScript bindings and remote stylesheets, as exploited in the wild by a March 2009 eBay listing.
CVE-2008-5504 1 Mozilla 1 Firefox 2023-02-12 7.5 HIGH N/A
Mozilla Firefox 2.x before 2.0.0.19 allows remote attackers to run arbitrary JavaScript with chrome privileges via vectors related to the feed preview, a different vulnerability than CVE-2008-3836.
CVE-2008-5019 3 Canonical, Debian, Mozilla 3 Ubuntu Linux, Debian Linux, Firefox 2023-02-12 4.3 MEDIUM N/A
The session restore feature in Mozilla Firefox 3.x before 3.0.4 and 2.x before 2.0.0.18 allows remote attackers to violate the same origin policy to conduct cross-site scripting (XSS) attacks and execute arbitrary JavaScript with chrome privileges via unknown vectors.
CVE-2009-0356 1 Mozilla 2 Firefox, Seamonkey 2023-02-12 5.1 MEDIUM N/A
Mozilla Firefox before 3.0.6 and SeaMonkey do not block links to the (1) about:plugins and (2) about:config URIs from .desktop files, which allows user-assisted remote attackers to bypass the Same Origin Policy and execute arbitrary code with chrome privileges via vectors involving the URL field in a Desktop Entry section of a .desktop file, related to representation of about: URIs as jar:file:// URIs. NOTE: this issue exists because of an incomplete fix for CVE-2008-4582.
