CVE-2013-5597 1 Mozilla 5 Firefox, Firefox Esr, Seamonkey and 2 more 2018-10-30 10.0 HIGH N/A
Use-after-free vulnerability in the nsDocLoader::doStopDocumentLoad function in Mozilla Firefox before 25.0, Firefox ESR 17.x before 17.0.10 and 24.x before 24.1, Thunderbird before 24.1, Thunderbird ESR 17.x before 17.0.10, and SeaMonkey before 2.22 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via vectors involving a state-change event during an update of the offline cache.
CVE-2017-7805 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2018-10-16 5.0 MEDIUM 7.5 HIGH
During TLS 1.2 exchanges, handshake hashes are generated which point to a message buffer. This saved data is used for later messages but in some cases, the handshake transcript can exceed the space available in the current buffer, causing the allocation of a new buffer. This leaves a pointer pointing to the old, freed buffer, resulting in a use-after-free when handshake hashes are then calculated afterwards. This can result in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
CVE-2018-5147 2 Debian, Mozilla 3 Debian Linux, Firefox, Firefox Esr 2018-08-14 7.5 HIGH 9.8 CRITICAL
The libtremor library has the same flaw as CVE-2018-5146. This library is used by Firefox in place of libvorbis on Android and ARM platforms. This vulnerability affects Firefox ESR < 52.7.2 and Firefox < 59.0.1.
CVE-2017-7760 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2018-08-14 4.6 MEDIUM 7.8 HIGH
The Mozilla Windows updater modifies some files to be updated by reading the original file and applying changes to it. The location of the original file can be altered by a malicious user by passing a special path to the callback parameter through the Mozilla Maintenance Service, allowing the manipulation of files in the installation directory and privilege escalation by manipulating 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-2017-7763 3 Apple, Debian, Mozilla 5 Mac Os X, Debian Linux, Firefox and 2 more 2018-08-14 5.0 MEDIUM 5.3 MEDIUM
Default fonts on OS X display some Tibetan characters as whitespace. When used in the addressbar as part of an IDN this can be used for domain name spoofing attacks. Note: This attack only affects OS X operating systems. Other operating systems are unaffected. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2017-7764 2 Debian, Mozilla 4 Debian Linux, Firefox, Firefox Esr and 1 more 2018-08-13 5.0 MEDIUM 5.3 MEDIUM
Characters from the "Canadian Syllabics" unicode block can be mixed with characters from other unicode blocks in the addressbar instead of being rendered as their raw "punycode" form, allowing for domain name spoofing attacks through character confusion. The current Unicode standard allows characters from "Aspirational Use Scripts" such as Canadian Syllabics to be mixed with Latin characters in the "moderately restrictive" IDN profile. We have changed Firefox behavior to match the upcoming Unicode version 10.0 which removes this category and treats them as "Limited Use Scripts.". This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2017-7778 3 Debian, Mozilla, Sil 5 Debian Linux, Firefox, Firefox Esr and 2 more 2018-08-13 7.5 HIGH 9.8 CRITICAL
A number of security vulnerabilities in the Graphite 2 library including out-of-bounds reads, buffer overflow reads and writes, and the use of uninitialized memory. These issues were addressed in Graphite 2 version 1.3.10. This vulnerability affects Firefox < 54, Firefox ESR < 52.2, and Thunderbird < 52.2.
CVE-2017-7768 2 Microsoft, Mozilla 3 Windows, Firefox, Firefox Esr 2018-08-13 2.1 LOW 5.5 MEDIUM
The Mozilla Maintenance Service can be invoked by an unprivileged user to read 32 bytes of any arbitrary file on the local system by convincing the service that it is reading a status file provided by the Mozilla Windows Updater. The Mozilla Maintenance Service executes with privileged access, bypassing system protections against unprivileged users. 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-2016-9902 2 Mozilla, Redhat 7 Firefox, Firefox Esr, Enterprise Linux Desktop and 4 more 2018-08-09 5.0 MEDIUM 7.5 HIGH
The Pocket toolbar button, once activated, listens for events fired from it's own pages but does not verify the origin of incoming events. This allows content from other origins to fire events and inject content and commands into the Pocket context. Note: this issue does not affect users with e10s enabled. This vulnerability affects Firefox ESR < 45.6 and Firefox < 50.1.
CVE-2018-5091 4 Canonical, Debian, Mozilla and 1 more 10 Ubuntu Linux, Debian Linux, Firefox and 7 more 2018-08-09 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur during WebRTC connections when interacting with the DTMF timers. This results in a potentially exploitable crash. This vulnerability affects Firefox ESR < 52.6 and Firefox < 58.
CVE-2017-7845 2 Microsoft, Mozilla 4 Windows, Firefox, Firefox Esr and 1 more 2018-08-09 9.3 HIGH 8.8 HIGH
A buffer overflow occurs when drawing and validating elements using Direct 3D 9 with the ANGLE graphics library, used for WebGL content. This is due to an incorrect value being passed within the library during checks and results in a potentially exploitable crash. Note: This attack only affects Windows operating systems. Other operating systems are unaffected. This vulnerability affects Thunderbird < 52.5.2, Firefox ESR < 52.5.2, and Firefox < 57.0.2.
CVE-2017-7824 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2018-08-09 7.5 HIGH 9.8 CRITICAL
A buffer overflow occurs when drawing and validating elements with the ANGLE graphics library, used for WebGL content. This is due to an incorrect value being passed within the library during checks and results in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
CVE-2017-7823 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2018-08-09 4.3 MEDIUM 5.4 MEDIUM
The content security policy (CSP) "sandbox" directive did not create a unique origin for the document, causing it to behave as if the "allow-same-origin" keyword were always specified. This could allow a Cross-Site Scripting (XSS) attack to be launched from unsafe content. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
CVE-2017-7819 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2018-08-09 7.5 HIGH 9.8 CRITICAL
A use-after-free vulnerability can occur in design mode when image objects are resized if objects referenced during the resizing have been freed from memory. This results in a potentially exploitable crash. This vulnerability affects Firefox < 56, Firefox ESR < 52.4, and Thunderbird < 52.4.
CVE-2017-7818 3 Debian, Mozilla, Redhat 9 Debian Linux, Firefox, Firefox Esr and 6 more 2018-08-09 7.5 HIGH 9.8 CRITICAL

CVE-2017-5466 2 Mozilla, Redhat 9 Firefox, Firefox Esr, Thunderbird and 6 more 2018-08-09 4.3 MEDIUM 6.1 MEDIUM
If a page is loaded from an original site through a hyperlink and contains a redirect to a "data:text/html" URL, triggering a reload will run the reloaded "data:text/html" page with its origin set incorrectly. This allows for a cross-site scripting (XSS) attack. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-5454 2 Mozilla, Redhat 9 Firefox, Firefox Esr, Thunderbird and 6 more 2018-08-09 5.0 MEDIUM 7.5 HIGH
A mechanism to bypass file system access protections in the sandbox to use the file picker to access different files than those selected in the file picker through the use of relative paths. This allows for read only access to the local file system. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
CVE-2017-5451 2 Mozilla, Redhat 9 Firefox, Firefox Esr, Thunderbird and 6 more 2018-08-09 4.3 MEDIUM 4.3 MEDIUM
A mechanism to spoof the addressbar through the user interaction on the addressbar and the "onblur" event. The event could be used by script to affect text display to make the loaded site appear to be different from the one actually loaded within the addressbar. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
