Mozilla: URL spoofing with right-to-left text aligned left-to-right (MFSA 2018-03)

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.

Mozilla: Windows Defender SmartScreen UI runs with less secure behavior for downloaded files in Windows 10 April 2018 Update

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 for a decision, and if the user is offline all files will be allowed to be opened because Windows won't prompt the user to ask what to do. Firefox incorrectly sets this flag when downloading files, leading to less secure behavior from SmartScreen. Note: this issue only affects Windows 10 users running the April 2018 update or later. It does not affect other Windows users or other operating systems. This vulnerability affects Thunderbird < 52.8, Thunderbird ESR < 52.8, Firefox < 60, and Firefox ESR < 52.8.

Content Spoofing in Multiple WSO2 Products via Error Message Injection

A content spoofing vulnerability exists in multiple WSO2 products due to improper error message handling. Under certain conditions, error messages are passed through URL parameters without validation, allowing malicious actors to inject arbitrary content into the UI. By exploiting this vulnerability, attackers can manipulate browser-displayed error messages, enabling social engineering attacks through deceptive or misleading content.
