| CVE | Vendors | Products | Updated | CVSS v3.1 |
|---|---|---|---|---|
| CVE-2020-6817 | 1 Mozilla | 1 Bleach | 2024-08-04 | 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-2020-6794 | 3 Canonical, Mozilla, Redhat | 4 Ubuntu Linux, Thunderbird, Enterprise Linux and 1 more | 2024-08-04 | 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-2020-6795 | 2 Mozilla, Redhat | 3 Thunderbird, Enterprise Linux, Rhel E4s | 2024-08-04 | 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-2020-6801 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-08-04 | 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-2020-6797 | 2 Apple, Mozilla | 4 Macos, Firefox, Firefox Esr and 1 more | 2024-08-04 | 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-2020-6823 | 1 Mozilla | 1 Firefox | 2024-08-04 | 9.8 Critical |
| A malicious extension could have called <code>browser.identity.launchWebAuthFlow</code>, controlling the redirect_uri, and through the Promise returned, obtain the Auth code and gain access to the user's account at the service provider. This vulnerability affects Firefox < 75. | ||||
| CVE-2020-6804 | 1 Mozilla | 1 Webthings Gateway | 2024-08-04 | 8.8 High |
| A reflected XSS vulnerability exists within the gateway, allowing an attacker to craft a specialized URL which could steal the user's authentication token. When combined with CVE-2020-6803, an attacker could fully compromise the system. | ||||
| CVE-2020-6815 | 1 Mozilla | 1 Firefox | 2024-08-04 | 9.8 Critical |
| Mozilla developers reported memory safety and script safety bugs present in Firefox 73. Some of these bugs showed evidence of memory corruption or escalation of privilege and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability affects Firefox < 74. | ||||
| CVE-2020-6807 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-08-04 | 8.8 High |
| When a device was changed while a stream was about to be destroyed, the <code>stream-reinit</code> task may have been executed after the stream was destroyed, causing a use-after-free and a potentially exploitable crash. This vulnerability affects Thunderbird < 68.6, Firefox < 74, Firefox < ESR68.6, and Firefox ESR < 68.6. | ||||
| CVE-2020-6809 | 1 Mozilla | 1 Firefox | 2024-08-04 | 7.5 High |
| When a Web Extension had the all-urls permission and made a fetch request with a mode set to 'same-origin', it was possible for the Web Extension to read local files. This vulnerability affects Firefox < 74. | ||||
| CVE-2020-6792 | 3 Canonical, Mozilla, Redhat | 4 Ubuntu Linux, Thunderbird, Enterprise Linux and 1 more | 2024-08-04 | 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-2020-6826 | 1 Mozilla | 1 Firefox | 2024-08-04 | 9.8 Critical |
| Mozilla developers Tyson Smith, Bob Clary, and Alexandru Michis reported memory safety bugs present in Firefox 74. 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 < 75. | ||||
| CVE-2020-6800 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-08-04 | 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-2020-6831 | 5 Canonical, Debian, Mozilla and 2 more | 10 Ubuntu Linux, Debian Linux, Firefox and 7 more | 2024-08-04 | 9.8 Critical |
| A buffer overflow could occur when parsing and validating SCTP chunks in WebRTC. This could have led to memory corruption and a potentially exploitable crash. This vulnerability affects Firefox ESR < 68.8, Firefox < 76, and Thunderbird < 68.8.0. | ||||
| CVE-2020-6816 | 2 Fedoraproject, Mozilla | 2 Fedora, Bleach | 2024-08-04 | 6.1 Medium |
| In Mozilla Bleach before 3.12, a mutation XSS in bleach.clean when RCDATA and either svg or math tags are whitelisted and the keyword argument strip=False. | ||||
| CVE-2020-6799 | 2 Microsoft, Mozilla | 3 Windows, Firefox, Firefox Esr | 2024-08-04 | 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. | ||||
| CVE-2020-6798 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-04 | 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-2020-6803 | 1 Mozilla | 1 Webthings Gateway | 2024-08-04 | 5.4 Medium |
| An open redirect is present on the gateway's login page, which could cause a user to be redirected to a malicious site after logging in. | ||||
| CVE-2020-6822 | 2 Mozilla, Redhat | 5 Firefox, Firefox Esr, Thunderbird and 2 more | 2024-08-04 | 8.8 High |
| On 32-bit builds, an out of bounds write could have occurred when processing an image larger than 4 GB in <code>GMPDecodeData</code>. It is possible that with enough effort this could have been exploited to run arbitrary code. This vulnerability affects Thunderbird < 68.7.0, Firefox ESR < 68.7, and Firefox < 75. | ||||
| CVE-2020-6805 | 3 Canonical, Mozilla, Redhat | 6 Ubuntu Linux, Firefox, Firefox Esr and 3 more | 2024-08-04 | 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. | ||||
