VCID-cxxg-uk18-pqhq 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. CVE-2017-7821
VCID-dh3c-g3k3-zkb7 Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7805
VCID-dydk-9hwf-4ka4 Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7793
VCID-e36h-6n36-puht Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7814
VCID-kvxt-7wyx-dfbr WebExtensions could use popups and panels in the extension UI to load an about: privileged URL, violating security checks that disallow this behavior. CVE-2017-7816
VCID-m3w6-89ms-z3fk 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. CVE-2017-7822
VCID-nfr9-wq4n-97df If web content on a page is dragged onto portions of the browser UI, such as the tab bar, links can be opened that otherwise would not be allowed to open. This can allow malicious web content to open a locally stored file through file: URLs. CVE-2017-7812
VCID-qwvy-9yec-dybk The instanceof operator can bypass the Xray wrapper mechanism. When called on web content from the browser itself or an extension the web content can provide its own result for that operator, possibly tricking the browser or extension into mishandling the element. CVE-2017-7820
VCID-u584-a1yu-jqcf Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7824
VCID-u8sk-mm4g-ffem Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7823
VCID-wfn6-c2ap-y3g4 Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7810
VCID-yaz5-6485-u7c1 Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7818
VCID-ykzd-mar6-r3c5 Multiple vulnerabilities have been found in Mozilla Thunderbird, the worst of which could lead to the execution of arbitrary code. CVE-2017-7819
VCID-yzz5-as7s-nkaf On pages containing an iframe, the data: protocol can be used to create a modal dialog through Javascript that will have an arbitrary domains as the dialog's location, spoofing of the origin of the modal dialog from the user view. *Note: This attack only affects installations with e10 multiprocess turned off. Installations with e10s turned on do not support the modal dialog functionality.* CVE-2017-7815
VCID-z5mk-4spk-1yc1 Inside the JavaScript parser, a cast of an integer to a narrower type can result in data read from outside the buffer being parsed. This usually results in a non-exploitable crash, but can leak a limited amount of information from memory if it matches JavaScript identifier syntax. CVE-2017-7813
VCID-zhen-yj1c-u3d6 Mozilla developers and community members Christian Holler, Jason Kratzer, Tobias Schneider, Tyson Smith, David Keeler, Nicolas B. Pierron, Mike Hommey, Ronald Crane, Tooru Fujisawa, and Philipp reported memory safety bugs present in Firefox 55. Some of these bugs showed evidence of memory corruption and we presume that with enough effort that some of these could be exploited to run arbitrary code. CVE-2017-7811
