CVE-2020-6806 3 Canonical, Mozilla, Redhat 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more 2024-11-21 8.8 High
By carefully crafting promise resolutions, it was possible to cause an out-of-bounds read off the end of an array resized during script execution. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
CVE-2020-6805 3 Canonical, Mozilla, Redhat 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more 2024-11-21 8.8 High
When removing data about an origin whose tab was recently closed, a use-after-free could occur in the Quota manager, resulting in a potentially exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6.
CVE-2020-6800 3 Canonical, Mozilla, Redhat 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more 2024-11-21 8.8 High
Mozilla developers and community members reported memory safety bugs present in Firefox 72 and Firefox ESR 68.4. 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. In general, these flaws cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but are potentially risks in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
CVE-2020-6798 2 Mozilla, Redhat 5 Firefox, Firefox Esr, Thunderbird and 2 more 2024-11-21 6.1 Medium
If a template tag was used in a select tag, the parser could be confused and allow JavaScript parsing and execution when it should not be allowed. A site that relied on the browser behaving correctly could suffer a cross-site scripting vulnerability as a result. In general, this flaw cannot be exploited through email in the Thunderbird product because scripting is disabled when reading mail, but is potentially a risk in browser or browser-like contexts. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
CVE-2020-6797 2 Apple, Mozilla 4 Macos, Firefox, Firefox Esr and 1 more 2024-11-21 4.3 Medium
By downloading a file with the .fileloc extension, a semi-privileged extension could launch an arbitrary application on the user's computer. The attacker is restricted as they are unable to download non-quarantined files or supply command line arguments to the application, limiting the impact. Note: this issue only occurs on Mac OSX. Other operating systems are unaffected. This vulnerability affects Thunderbird < 68.5, Firefox < 73, and Firefox < ESR68.5.
CVE-2020-6795 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel E4s 2024-11-21 6.5 Medium
When processing a message that contains multiple S/MIME signatures, a bug in the MIME processing code caused a null pointer dereference, leading to an unexploitable crash. This vulnerability affects Thunderbird < 68.5.
CVE-2020-6794 3 Canonical, Mozilla, Redhat 4 Ubuntu Linux, Thunderbird, Enterprise Linux and 1 more 2024-11-21 6.5 Medium
If a user saved passwords before Thunderbird 60 and then later set a master password, an unencrypted copy of these passwords is still accessible. This is because the older stored password file was not deleted when the data was copied to a new format starting in Thunderbird 60. The new master password is added only on the new file. This could allow the exposure of stored password data outside of user expectations. This vulnerability affects Thunderbird < 68.5.
CVE-2020-6793 2 Mozilla, Redhat 3 Thunderbird, Enterprise Linux, Rhel E4s 2024-11-21 6.5 Medium
When processing an email message with an ill-formed envelope, Thunderbird could read data from a random memory location. This vulnerability affects Thunderbird < 68.5.
CVE-2020-6792 3 Canonical, Mozilla, Redhat 4 Ubuntu Linux, Thunderbird, Enterprise Linux and 1 more 2024-11-21 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-2020-35113 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
Mozilla developers reported memory safety bugs present in Firefox 83 and Firefox ESR 78.5. 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 < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-35112 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-11-21 8.8 High
If a user downloaded a file lacking an extension on Windows, and then "Open"-ed it from the downloads panel, if there was an executable file in the downloads directory with the same name but with an executable extension (such as .bat or .exe) that executable would have been launched instead. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-35111 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 4.3 Medium
When an extension with the proxy permission registered to receive <all_urls>, the proxy.onRequest callback was not triggered for view-source URLs. While web content cannot navigate to such URLs, a user opening View Source could have inadvertently leaked their IP address. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-26978 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.1 Medium
Using techniques that built on the slipstream research, a malicious webpage could have exposed both an internal network's hosts as well as services running on the user's local machine. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-26974 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
When flex-basis was used on a table wrapper, a StyleGenericFlexBasis object could have been incorrectly cast to the wrong type. This resulted in a heap user-after-free, memory corruption, and a potentially exploitable crash. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-26973 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
Certain input to the CSS Sanitizer confused it, resulting in incorrect components being removed. This could have been used as a sanitizer bypass. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-26971 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
Certain blit values provided by the user were not properly constrained leading to a heap buffer overflow on some video drivers. This vulnerability affects Firefox < 84, Thunderbird < 78.6, and Firefox ESR < 78.6.
CVE-2020-26970 2 Mozilla, Redhat 4 Thunderbird, Enterprise Linux, Rhel E4s and 1 more 2024-11-21 8.8 High
When reading SMTP server status codes, Thunderbird writes an integer value to a position on the stack that is intended to contain just one byte. Depending on processor architecture and stack layout, this leads to stack corruption that may be exploitable. This vulnerability affects Thunderbird < 78.5.1.
CVE-2020-26968 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 8.8 High
Mozilla developers reported memory safety bugs present in Firefox 82 and Firefox ESR 78.4. 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 < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26966 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2024-11-21 6.5 Medium
Searching for a single word from the address bar caused an mDNS request to be sent on the local network searching for a hostname consisting of that string; resulting in an information leak. *Note: This issue only affected Windows operating systems. Other operating systems are unaffected.*. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
CVE-2020-26965 2 Mozilla, Redhat 6 Firefox, Firefox Esr, Thunderbird and 3 more 2024-11-21 6.5 Medium
Some websites have a feature "Show Password" where clicking a button will change a password field into a textbook field, revealing the typed password. If, when using a software keyboard that remembers user input, a user typed their password and used that feature, the type of the password field was changed, resulting in a keyboard layout change and the possibility for the software keyboard to remember the typed password. This vulnerability affects Firefox < 83, Firefox ESR < 78.5, and Thunderbird < 78.5.
