CVE-2018-5137 | CWE-200 | Information Leak / Disclosure | 7.5 |
A legacy extension's non-contentaccessible, defined resources can be loaded by an arbitrary web page through script. This script does this by using a maliciously crafted path string to reference the resources. Note: this vulnerability does not affect WebExtensions. This vulnerability affects Firefox < 59. |
|||
CVE-2018-5136 | CWE-20 | Input Validation | 7.5 |
A shared worker created from a "data:" URL in one tab can be shared by another tab with a different origin, bypassing the same-origin policy. This vulnerability affects Firefox < 59. |
|||
CVE-2018-5135 | CWE-284 | Improper Access Control | 7.5 |
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-2018-5134 | CWE-200 | Information Leak / Disclosure | 7.5 |
WebExtensions may use "view-source:" URLs to view local "file:" URL content, as well as content stored in "about:cache", bypassing restrictions that only allow WebExtensions to view specific content. This vulnerability affects Firefox < 59. |
|||
CVE-2018-5133 | CWE-200 | Information Leak / Disclosure | 6.5 |
If the "app.support.baseURL" preference is changed by a malicious local program to contain HTML and script content, this content is not sanitized. It will be executed if a user loads "chrome://browser/content/preferences/in-content/preferences.xul" directly in a tab and executes a search. This stored preference is also executed whenever an EME video player plugin displays a CDM-disabled message as a notification message. This vulnerability affects Firefox < 59. |
|||
CVE-2018-5132 | CWE-200 | Information Leak / Disclosure | 6.5 |
The Find API for WebExtensions can search some privileged pages, such as "about:debugging", if these pages are open in a tab. This could allow a malicious WebExtension to search for otherwise protected data if a user has it open. This vulnerability affects Firefox < 59. |
|||
CVE-2018-5131 | CWE-200 | Information Leak / Disclosure | 5.9 |
Under certain circumstances the "fetch()" API can return transient local copies of resources that were sent with a "no-store" or "no-cache" cache header instead of downloading a copy from the network as it should. This can result in previously stored, locally cached data of a website being accessible to users if they share a common profile while browsing. This vulnerability affects Firefox ESR < 52.7 and Firefox < 59. |
|||
CVE-2018-5130 | CWE-20 | Input Validation | 8.8 |
When packets with a mismatched RTP payload type are sent in WebRTC connections, in some circumstances a potentially exploitable crash is triggered. This vulnerability affects Firefox ESR < 52.7 and Firefox < 59. |
|||
CVE-2018-5129 | CWE-787 | Out-of-bounds Write | 8.6 |
A lack of parameter validation on IPC messages results in a potential out-of-bounds write through malformed IPC messages. This can potentially allow for sandbox escape through memory corruption in the parent process. This vulnerability affects Thunderbird < 52.7, Firefox ESR < 52.7, and Firefox < 59. |
|||
CVE-2018-5128 | CWE-416 | Use After Free | 9.8 |
A use-after-free vulnerability can occur when manipulating elements, events, and selection ranges during editor operations. This results in a potentially exploitable crash. This vulnerability affects Firefox < 59. |
