| CVE-2018-5177 | Hig | 0.49 | 7.5 | 0.04 | Jun 11, 2018 | A vulnerability exists in XSLT during number formatting where a negative buffer size may be allocated in some instances, leading to a buffer overflow and crash if it occurs. This vulnerability affects Firefox < 60. | ||
| CVE-2018-5174 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | In the Windows 10 April 2018 Update, Windows Defender SmartScreen honors the "SEE_MASK_FLAG_NO_UI" flag associated with downloaded files and will not show any UI. Files that are unknown and potentially dangerous will be allowed to run because SmartScreen will not prompt the user… | ||
| CVE-2018-5166 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | WebExtensions can use request redirection and a "filterReponseData" filter to bypass host permission settings to redirect network traffic and access content from a host for which they do not have explicit user permission. This vulnerability affects Firefox < 60. | ||
| CVE-2018-5160 | Hig | 0.49 | 7.5 | 0.03 | Jun 11, 2018 | WebRTC can use a "WrappedI420Buffer" pixel buffer but the owning image object can be freed while it is still in use.

| CVE-2018-5135 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | 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 <… | ||
| CVE-2018-5134 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | 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-2018-5115 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | If an HTTP authentication prompt is triggered by a background network request from a page or extension, it is displayed over the currently loaded foreground page. Although the prompt contains the real domain making the request, this can result in user confusion about the… | ||
| CVE-2018-5113 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | The "browser.identity.launchWebAuthFlow" function of WebExtensions is only allowed to load content over "https:" but this requirement was not properly enforced.

| CVE-2018-5112 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | Development Tools panels of an extension are required to load URLs for the panels as relative URLs from the extension manifest file but this requirement was not enforced in all instances. This could allow the development tools panel for the extension to load a URL that it should… | ||
| CVE-2018-5101 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | A use-after-free vulnerability can occur when manipulating floating "first-letter" style elements, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 58. | ||
| CVE-2018-5100 | Hig | 0.49 | 7.5 | 0.05 | Jun 11, 2018 | A use-after-free vulnerability can occur when arguments passed to the "IsPotentiallyScrollable" function are freed while still in use by scripts. This results in a potentially exploitable crash. This vulnerability affects Firefox < 58. | ||
| CVE-2017-7843 | Hig | 0.49 | 7.5 | 0.03 | Jun 11, 2018 | When Private Browsing mode is used, it is possible for a web worker to write persistent data to IndexedDB and fingerprint a user uniquely. IndexedDB should not be available in Private Browsing mode and this stored data will persist across multiple private browsing mode sessions… | ||
| CVE-2017-7806 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | A use-after-free vulnerability can occur when the layer manager is freed too early when rendering specific SVG content, resulting in a potentially exploitable crash. This vulnerability affects Firefox < 55. | ||
| CVE-2017-7805 | Hig | 0.49 | 7.5 | 0.03 | Jun 11, 2018 | 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… | ||
| CVE-2017-7804 | Hig | 0.49 | 7.5 | 0.01 | Jun 11, 2018 | The destructor function for the "WindowsDllDetourPatcher" class can be re-purposed by malicious code in concert with another vulnerability to write arbitrary data to an attacker controlled location in memory. This can be used to bypass existing memory protections in this… | ||
| CVE-2017-7803 | Hig | 0.49 | 7.5 | 0.02 | Jun 11, 2018 | 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. |
