CVE-2021-38491 1 Mozilla 1 Firefox 2022-03-16 4.3 MEDIUM 6.5 MEDIUM
Mixed-content checks were unable to analyze opaque origins which led to some mixed content being loaded. This vulnerability affects Firefox < 92.
CVE-2021-29987 2 Linux, Mozilla 3 Linux Kernel, Firefox, Thunderbird 2022-03-16 4.3 MEDIUM 6.5 MEDIUM
After requesting multiple permissions, and closing the first permission panel, subsequent permission panels will be displayed in a different position but still record a click in the default location, making it possible to trick a user into accepting a permission they did not want to. *This bug only affects Firefox on Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 91 and Thunderbird < 91.
CVE-2021-29982 1 Mozilla 2 Firefox, Thunderbird 2022-03-16 4.3 MEDIUM 6.5 MEDIUM
Due to incorrect JIT optimization, we incorrectly interpreted data from the wrong type of object, resulting in the potential leak of a single bit of memory. This vulnerability affects Firefox < 91 and Thunderbird < 91.
CVE-2021-29981 1 Mozilla 2 Firefox, Thunderbird 2022-03-16 6.8 MEDIUM 8.8 HIGH
An issue present in lowering/register allocation could have led to obscure but deterministic register confusion failures in JITted code that would lead to a potentially exploitable crash. This vulnerability affects Firefox < 91 and Thunderbird < 91.
CVE-2021-29977 1 Mozilla 1 Firefox 2022-03-16 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 89. 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 < 90.
CVE-2021-29975 1 Mozilla 1 Firefox 2022-03-16 4.3 MEDIUM 6.5 MEDIUM
Through a series of DOM manipulations, a message, over which the attacker had control of the text but not HTML or formatting, could be overlaid on top of another domain (with the new domain correctly shown in the address bar) resulting in possible user confusion. This vulnerability affects Firefox < 90.
CVE-2021-29974 1 Mozilla 1 Firefox 2022-03-16 2.6 LOW 4.3 MEDIUM
When network partitioning was enabled, e.g. as a result of Enhanced Tracking Protection settings, a TLS error page would allow the user to override an error on a domain which had specified HTTP Strict Transport Security (which implies that the error should not be override-able.) This issue did not affect the network connections, and they were correctly upgraded to HTTPS automatically. This vulnerability affects Firefox < 90.
CVE-2004-2659 2 Mozilla, Opera 2 Mozilla, Opera Browser 2022-02-28 4.0 MEDIUM N/A
Opera offers an Open button to verify that a user wishes to execute a downloaded file, which allows user-assisted remote attackers to construct a race condition that tricks a user into clicking Open via a request for a different mouse or keyboard action very shortly before the Open dialog appears. NOTE: this is a different issue than CVE-2005-2407.
CVE-2005-0238 4 Gnome, Mozilla, Omnigroup and 1 more 5 Epiphany, Camino, Mozilla and 2 more 2022-02-28 5.0 MEDIUM N/A
The International Domain Name (IDN) support in Epiphany allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks.
CVE-2005-0233 4 Mozilla, Omnigroup, Opera and 1 more 6 Camino, Firefox, Mozilla and 3 more 2022-02-28 7.5 HIGH N/A
The International Domain Name (IDN) support in Firefox 1.0, Camino .8.5, and Mozilla before 1.7.6 allows remote attackers to spoof domain names using punycode encoded domain names that are decoded in URLs and SSL certificates in a way that uses homograph characters from other character sets, which facilitates phishing attacks.
CVE-2007-0802 2 Mozilla, Opera 2 Firefox, Opera Browser 2022-02-26 6.4 MEDIUM N/A
Mozilla Firefox 2.0.0.1 allows remote attackers to bypass the Phishing Protection mechanism by adding certain characters to the end of the domain name, as demonstrated by the "." and "/" characters, which is not caught by the Phishing List blacklist filter.
CVE-2007-1377 4 Adobe, Mozilla, Netscape and 1 more 4 Acrobat Reader, Firefox, Navigator and 1 more 2022-02-26 5.0 MEDIUM N/A
AcroPDF.DLL in Adobe Reader 8.0, when accessed from Mozilla Firefox, Netscape, or Opera, allows remote attackers to cause a denial of service (unspecified resource consumption) via a .pdf URL with an anchor identifier that begins with search= followed by many %n sequences, a different vulnerability than CVE-2006-6027 and CVE-2006-6236.
CVE-2020-15660 1 Mozilla 1 Geckodriver 2022-02-22 6.8 MEDIUM 8.8 HIGH
Missing checks on Content-Type headers in geckodriver before 0.27.0 could lead to a CSRF vulnerability, that might, when paired with a specifically prepared request, lead to remote code execution.
CVE-2020-12398 2 Canonical, Mozilla 2 Ubuntu Linux, Thunderbird 2022-01-04 4.3 MEDIUM 7.5 HIGH
If Thunderbird is configured to use STARTTLS for an IMAP server, and the server sends a PREAUTH response, then Thunderbird will continue with an unencrypted connection, causing email data to be sent without protection. This vulnerability affects Thunderbird < 68.9.0.
CVE-2020-12399 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2022-01-04 1.2 LOW 4.4 MEDIUM
NSS has shown timing differences when performing DSA signatures, which was exploitable and could eventually leak private keys. This vulnerability affects Thunderbird < 68.9.0, Firefox < 77, and Firefox ESR < 68.9.
CVE-2019-11764 2 Canonical, Mozilla 4 Ubuntu Linux, Firefox, Firefox Esr and 1 more 2022-01-01 6.8 MEDIUM 8.8 HIGH
Mozilla developers and community members reported memory safety bugs present in Firefox 69 and Firefox ESR 68.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could be exploited to run arbitrary code. This vulnerability affects Firefox < 70, Thunderbird < 68.2, and Firefox ESR < 68.2.
CVE-2019-17021 3 Microsoft, Mozilla, Opensuse 4 Windows, Firefox, Firefox Esr and 1 more 2022-01-01 2.6 LOW 5.3 MEDIUM
During the initialization of a new content process, a race condition occurs that can allow a content process to disclose heap addresses from the parent process. *Note: this issue only occurs on Windows. Other operating systems are unaffected.*. This vulnerability affects Firefox ESR < 68.4 and Firefox < 72.
CVE-2020-6792 2 Canonical, Mozilla 2 Ubuntu Linux, Thunderbird 2022-01-01 4.3 MEDIUM 4.3 MEDIUM
When deriving an identifier for an email message, uninitialized memory was used in addition to the message contents. This vulnerability affects Thunderbird < 68.5.
CVE-2020-6801 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2022-01-01 6.8 MEDIUM 8.8 HIGH
Mozilla developers reported memory safety bugs present in Firefox 72. 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 < 73.
CVE-2020-6799 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2022-01-01 5.1 MEDIUM 8.8 HIGH
Command line arguments could have been injected during Firefox invocation as a shell handler for certain unsupported file types. This required Firefox to be configured as the default handler for a given file type and for a file downloaded to be opened in a third party application that insufficiently sanitized URL data. In that situation, clicking a link in the third party application could have been used to retrieve and execute files whose location was supplied through command line arguments. Note: This issue only affects Windows operating systems and when Firefox is configured as the default handler for non-default filetypes. Other operating systems are unaffected. This vulnerability affects Firefox < 73 and Firefox < ESR68.5.
