CVE-2017-5426 2 Linux, Mozilla 3 Linux Kernel, Firefox, Thunderbird 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
On Linux, if the secure computing mode BPF (seccomp-bpf) filter is running when the Gecko Media Plugin sandbox is started, the sandbox fails to be applied and items that would run within the sandbox are run protected only by the running filter which is typically weak compared to the sandbox. Note: this issue only affects Linux. Other operating systems are not affected. This vulnerability affects Firefox < 52 and Thunderbird < 52.
CVE-2017-7836 3 Apple, Linux, Mozilla 3 Mac Os X, Linux Kernel, Firefox 2019-10-02 4.6 MEDIUM 7.8 HIGH
The "pingsender" executable used by the Firefox Health Report dynamically loads a system copy of libcurl, which an attacker could replace. This allows for privilege escalation as the replaced libcurl code will run with Firefox's privileges. Note: This attack requires an attacker have local system access and only affects OS X and Linux. Windows systems are not affected. This vulnerability affects Firefox < 57.
CVE-2018-5135 1 Mozilla 1 Firefox 2019-10-02 5.0 MEDIUM 7.5 HIGH
WebExtensions can bypass normal restrictions in some circumstances and use "browser.tabs.executeScript" to inject scripts into contexts where this should not be allowed, such as pages from other WebExtensions or unprivileged "about:" pages. This vulnerability affects Firefox < 59.
CVE-2017-7830 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
The Resource Timing API incorrectly revealed navigations in cross-origin iframes. This is a same-origin policy violation and could allow for data theft of URLs loaded by users. This vulnerability affects Firefox < 57, Firefox ESR < 52.5, and Thunderbird < 52.5.
CVE-2017-7761 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2019-10-02 3.6 LOW 5.5 MEDIUM
The Mozilla Maintenance Service "helper.exe" application creates a temporary directory writable by non-privileged users. When this is combined with creation of a junction (a form of symbolic link), protected files in the target directory of the junction can be deleted by the Mozilla Maintenance Service, which has privileged access. Note: This attack requires local system access and only affects Windows. Other operating systems are not affected. This vulnerability affects Firefox ESR < 52.2 and Firefox < 54.
CVE-2017-7822 1 Mozilla 1 Firefox 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
The AES-GCM implementation in WebCrypto API accepts 0-length IV when it should require a length of 1 according to the NIST Special Publication 800-38D specification. This might allow for the authentication key to be determined in some instances. This vulnerability affects Firefox < 56.
CVE-2017-5386 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2019-10-02 7.5 HIGH 7.3 HIGH
WebExtension scripts can use the "data:" protocol to affect pages loaded by other web extensions using this protocol, leading to potential data disclosure or privilege escalation in affected extensions. This vulnerability affects Firefox ESR < 45.7 and Firefox < 51.
CVE-2017-7821 1 Mozilla 1 Firefox 2019-10-02 7.5 HIGH 9.8 CRITICAL
A vulnerability where WebExtensions can download and attempt to open a file of some non-executable file types. This can be triggered without specific user interaction for the file download and open actions. This could be used to trigger known vulnerabilities in the programs that handle those document types. This vulnerability affects Firefox < 56.
CVE-2017-7803 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2019-10-02 5.0 MEDIUM 7.5 HIGH
When a page's content security policy (CSP) header contains a "sandbox" directive, other directives are ignored. This results in the incorrect enforcement of CSP. This vulnerability affects Thunderbird < 52.3, Firefox ESR < 52.3, and Firefox < 55.
CVE-2018-18505 4 Canonical, Debian, Mozilla and 1 more 11 Ubuntu Linux, Debian Linux, Firefox and 8 more 2019-10-02 7.5 HIGH 10.0 CRITICAL
An earlier fix for an Inter-process Communication (IPC) vulnerability, CVE-2011-3079, added authentication to communication between IPC endpoints and server parents during IPC process creation. This authentication is insufficient for channels created after the IPC process is started, leading to the authentication not being correctly applied to later channels. This could allow for a sandbox escape through IPC channels due to lack of message validation in the listener process. This vulnerability affects Thunderbird < 60.5, Firefox ESR < 60.5, and Firefox < 65.
CVE-2018-12402 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 4.3 MEDIUM 6.5 MEDIUM
The internal WebBrowserPersist code does not use correct origin context for a resource being saved. This manifests when sub-resources are loaded as part of "Save Page As..." functionality. For example, a malicious page could recover a visitor's Windows username and NTLM hash by including resources otherwise unreachable to the malicious page, if they can convince the visitor to save the complete web page. Similarly, SameSite cookies are sent on cross-origin requests when the "Save Page As..." menu item is selected to save a page, which can result in saving the wrong version of resources based on those cookies. This vulnerability affects Firefox < 63.
CVE-2018-5113 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 5.0 MEDIUM 7.5 HIGH
The "browser.identity.launchWebAuthFlow" function of WebExtensions is only allowed to load content over "https:" but this requirement was not properly enforced. This can potentially allow privileged pages to be loaded by the extension. This vulnerability affects Firefox < 58.
CVE-2017-5381 1 Mozilla 1 Firefox 2019-10-02 5.0 MEDIUM 7.5 HIGH
The "export" function in the Certificate Viewer can force local filesystem navigation when the "common name" in a certificate contains slashes, allowing certificate content to be saved in unsafe locations with an arbitrary filename. This vulnerability affects Firefox < 51.
CVE-2017-5462 2 Debian, Mozilla 5 Debian Linux, Firefox, Firefox Esr and 2 more 2019-10-02 5.0 MEDIUM 5.3 MEDIUM
A flaw in DRBG number generation within the Network Security Services (NSS) library where the internal state V does not correctly carry bits over. The NSS library has been updated to fix this issue to address this issue and Firefox ESR 52.1 has been updated with NSS version 3.28.4. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 45.9, Firefox ESR < 52.1, and Firefox < 53.
CVE-2018-5105 2 Canonical, Mozilla 2 Ubuntu Linux, Firefox 2019-10-02 7.2 HIGH 7.8 HIGH
WebExtensions can bypass user prompts to first save and then open an arbitrarily downloaded file. This can result in an executable file running with local user privileges without explicit user consent. This vulnerability affects Firefox < 58.
CVE-2018-5179 1 Mozilla 1 Firefox 2019-10-02 5.0 MEDIUM 7.5 HIGH
A service worker can send the activate event on itself periodically which allows it to run perpetually, allowing it to monitor activity by users. Affects all versions prior to Firefox 60.
CVE-2017-5456 2 Mozilla, Redhat 8 Firefox, Firefox Esr, Enterprise Linux and 5 more 2019-10-02 7.5 HIGH 9.8 CRITICAL
A mechanism to bypass file system access protections in the sandbox using the file system request constructor through an IPC message. This allows for read and write access to the local file system. This vulnerability affects Firefox ESR < 52.1 and Firefox < 53.
CVE-2018-10229 3 Google, Lg, Mozilla 3 Chrome, Nexus 5, Firefox 2019-10-02 5.8 MEDIUM 4.8 MEDIUM
A hardware vulnerability in GPU memory modules allows attackers to accelerate micro-architectural attacks through the use of the JavaScript WebGL API.
CVE-2017-7781 1 Mozilla 1 Firefox 2019-10-02 4.3 MEDIUM 5.9 MEDIUM
An error occurs in the elliptic curve point addition algorithm that uses mixed Jacobian-affine coordinates where it can yield a result "POINT_AT_INFINITY" when it should not. A man-in-the-middle attacker could use this to interfere with a connection, resulting in an attacked party computing an incorrect shared secret. This vulnerability affects Firefox < 55.
CVE-2017-5468 1 Mozilla 1 Firefox 2019-10-02 6.4 MEDIUM 9.1 CRITICAL
An issue with incorrect ownership model of "privateBrowsing" information exposed through developer tools. This can result in a non-exploitable crash when manually triggered during debugging. This vulnerability affects Firefox < 53.
