The drag-and-drop implementation in Google Chrome before 13.0.782.107 on Linux does not properly enforce permissions for files, which allows user-assisted remote attackers to bypass intended access restrictions via unspecified vectors.

Description: A permissions issue was addressed with improved validation. This issue is fixed in iOS 15.1 and iPadOS 15.1, tvOS 15.1, macOS Big Sur 11.6.2, watchOS 8.1, macOS Monterey 12.1. A malicious application may be able to bypass Privacy preferences.

Due to an unusual sequence of attacker-controlled events, a Javascript alert() dialog with arbitrary (although unstyled) contents could be displayed over top an uncontrolled webpage of the attacker's choosing. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.

The Opportunistic Encryption feature of HTTP2 (RFC 8164) allows a connection to be transparently upgraded to TLS while retaining the visual properties of an HTTP connection, including being same-origin with unencrypted connections on port 80. However, if a second encrypted port on the same IP address (e.g. port 8443) did not opt-in to opportunistic encryption; a network attacker could forward a connection from the browser to port 443 to port 8443, causing the browser to treat the content of port 8443 as same-origin with HTTP. This was resolved by disabling the Opportunistic Encryption feature, which had low usage. This vulnerability affects Firefox < 94, Thunderbird < 91.3, and Firefox ESR < 91.3.
