CVE-2018-5132 |
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. Published: June 11, 2018; 5:29:14 PM -0400 |

CVE-2018-5131 |
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. Published: June 11, 2018; 5:29:14 PM -0400 |

CVE-2018-5121 |
Low descenders on some Tibetan characters in several fonts on OS X are clipped when rendered in the addressbar. When used as part of an Internationalized Domain Name (IDN) this can be used for domain name spoofing attacks. Note: This attack only affects OS X operating systems.

CVE-2018-5118 |
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. Published: June 11, 2018; 5:29:13 PM -0400 |

CVE-2018-5117 |
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. Published: June 11, 2018; 5:29:13 PM -0400 |

CVE-2018-5116 |
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. Published: June 11, 2018; 5:29:13 PM -0400 |

CVE-2018-5115 |
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 originating site of the authentication request and may cause users to mistakenly send private credential information to a third party site. This vulnerability affects Firefox < 58. Published: June 11, 2018; 5:29:13 PM -0400 |
V4.0:(not available) V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2018-5114 |
If an existing cookie is changed to be "HttpOnly" while a document is open, the original value remains accessible through script until that document is closed. Network requests correctly use the changed HttpOnly cookie. This vulnerability affects Firefox < 58. Published: June 11, 2018; 5:29:13 PM -0400 |
V4.0:(not available) V3.0: 5.3 MEDIUM V2.0: 5.0 MEDIUM |
CVE-2018-5113 |
The "browser.identity.launchWebAuthFlow" function of WebExtensions is only allowed to load content over "https:" but this requirement was not properly enforced. This can potentially allow privileged pages to be loaded by the extension. This vulnerability affects Firefox < 58. Published: June 11, 2018; 5:29:13 PM -0400 |
V4.0:(not available) V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2018-5112 |
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 not be able to access, including potentially privileged pages. This vulnerability affects Firefox < 58. Published: June 11, 2018; 5:29:13 PM -0400 |
V4.0:(not available) V3.0: 7.5 HIGH V2.0: 5.0 MEDIUM |
CVE-2018-5111 |
When the text of a specially formatted URL is dragged to the addressbar from page content, the displayed URL can be spoofed to show a different site than the one loaded. This allows for phishing attacks where a malicious page can spoof the identify of another site. This vulnerability affects Firefox < 58. Published: June 11, 2018; 5:29:13 PM -0400 |
