|---|---|---|---|---|---|
| CVE-2018-5143 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 4.3 MEDIUM | 6.1 MEDIUM |
| URLs using "javascript:" have the protocol removed when pasted into the addressbar to protect users from cross-site scripting (XSS) attacks, but if a tab character is embedded in the "javascript:" URL the protocol is not removed and the script will execute. This could allow users to be socially engineered to run an XSS attack against themselves. This vulnerability affects Firefox < 59. | |||||
| CVE-2018-5142 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| If Media Capture and Streams API permission is requested from documents with "data:" or "blob:" URLs, the permission notifications do not properly display the originating domain. The notification states "Unknown protocol" as the requestee, leading to user confusion about which site is asking for this permission. This vulnerability affects Firefox < 59. | |||||
| CVE-2018-5141 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 6.4 MEDIUM | 8.2 HIGH |
| A vulnerability in the notifications Push API where notifications can be sent through service workers by web content without direct user interaction. This could be used to open new tabs in a denial of service (DOS) attack or to display unwanted content from arbitrary URLs to users. This vulnerability affects Firefox < 59. | |||||
| CVE-2018-5140 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| Image for moz-icons can be accessed through the "moz-icon:" protocol through script in web content even when otherwise prohibited. This could allow for information leakage of which applications are associated with specific MIME types by a malicious page. This vulnerability affects Firefox < 59. | |||||
| CVE-2018-5137 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2018-5133 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 4.3 MEDIUM | 6.5 MEDIUM |
| 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 | 4 Canonical, Debian, Mozilla and 1 more | 9 Ubuntu Linux, Debian Linux, Firefox and 6 more | 2024-11-21 | 4.3 MEDIUM | 5.9 MEDIUM |
| 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 | 4 Canonical, Debian, Mozilla and 1 more | 9 Ubuntu Linux, Debian Linux, Firefox and 6 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| 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 | 4 Canonical, Debian, Mozilla and 1 more | 10 Ubuntu Linux, Debian Linux, Firefox and 7 more | 2024-11-21 | 5.0 MEDIUM | 8.6 HIGH |
| 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 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| 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. | |||||
| CVE-2018-5127 | 4 Canonical, Debian, Mozilla and 1 more | 10 Ubuntu Linux, Debian Linux, Firefox and 7 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| A buffer overflow can occur when manipulating the SVG "animatedPathSegList" through script. This results in a potentially exploitable crash. This vulnerability affects Thunderbird < 52.7, Firefox ESR < 52.7, and Firefox < 59. | |||||
| CVE-2018-5126 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| Memory safety bugs were reported in Firefox 58. 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. This vulnerability affects Firefox < 59. | |||||
| CVE-2018-5125 | 4 Canonical, Debian, Mozilla and 1 more | 8 Ubuntu Linux, Debian Linux, Firefox and 5 more | 2024-11-21 | 6.8 MEDIUM | 8.8 HIGH |
| Memory safety bugs were reported in Firefox 58 and Firefox ESR 52.6. 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. This vulnerability affects Thunderbird < 52.7, Firefox ESR < 52.7, and Firefox < 59. | |||||
| CVE-2018-5122 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| A potential integer overflow in the "DoCrypt" function of WebCrypto was identified. If a means was found of exploiting it, it could result in an out-of-bounds write. This vulnerability affects Firefox < 58. | |||||
| CVE-2018-5119 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| The reader view will display cross-origin content when CORS headers are set to prohibit the loading of cross-origin content by a site. This could allow access to content that should be restricted in reader view. This vulnerability affects Firefox < 58. | |||||
| CVE-2018-5118 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| The screenshot images displayed in the Activity Stream page displayed when a new tab is opened is created from the meta tags of websites. An issue was discovered where the page could attempt to create these images through "file:" URLs from the local file system. This loading is blocked by the sandbox but could expose local data if combined with another attack that escapes sandbox protections. This vulnerability affects Firefox < 58. | |||||
| CVE-2018-5117 | 4 Canonical, Debian, Mozilla and 1 more | 11 Ubuntu Linux, Debian Linux, Firefox and 8 more | 2024-11-21 | 5.0 MEDIUM | 5.3 MEDIUM |
| If right-to-left text is used in the addressbar with left-to-right alignment, it is possible in some circumstances to scroll this text to spoof the displayed URL. This issue could result in the wrong URL being displayed as a location, which can mislead users to believe they are on a different site than the one loaded. This vulnerability affects Thunderbird < 52.6, Firefox ESR < 52.6, and Firefox < 58. | |||||
| CVE-2018-5116 | 2 Canonical, Mozilla | 2 Ubuntu Linux, Firefox | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| WebExtensions with the "ActiveTab" permission are able to access frames hosted within the active tab even if the frames are cross-origin. Malicious extensions can inject frames from arbitrary origins into the loaded page and then interact with them, bypassing same-origin user expectations with this permission. This vulnerability affects Firefox < 58. | |||||
