Mozilla Foundation Security Advisory 2021-23 Security Vulnerabilities fixed in Firefox 89 Announced June 1, 2021 Impact high Products Firefox Fixed in Firefox 89 #CVE-2021-29965: Password Manager on Firefox for Android susceptible to domain spoofing Reporter Harshit Mahendra Impact high Description A malicious website that causes an HTTP Authentication dialog to be spawned could trick the built-in password manager to suggest passwords for the currently active website instead of the website that triggered the dialog. This bug only affects Firefox for Android. Other operating systems are unaffected. References Bug 1709257 #CVE-2021-29960: Filenames printed from private browsing mode incorrectly retained in preferences Reporter Sebastian Hengst Impact moderate Description Firefox used to cache the last filename used for printing a file. When generating a filename for printing, Firefox usually suggests the web page title. The caching and suggestion techniques combined may have lead to the title of a website visited during private browsing mode being stored on disk. References Bug 1675965 #CVE-2021-29961: Firefox UI spoof using `select elements and CSS scaling Reporter Irvan Kurniawan Impact moderate Description When styling and rendering an oversized select element, Firefox did not apply correct clipping which allowed an attacker to paint over the user interface. References Bug 1700235 #CVE-2021-29963: Shared cookies for search suggestions in private browsing mode Reporter Wladimir Palant working with Include Security Impact moderate Description Address bar search suggestions in private browsing mode were re-using session data from normal mode. This bug only affects Firefox for Android. Other operating systems are unaffected. References Bug 1705068 #CVE-2021-29964: Out of bounds-read when parsing a `WM_COPYDATA` message Reporter Ronald Crane Impact moderate Description A locally-installed hostile program could send WM_COPYDATA messages that Firefox would process incorrectly, leading to an out-of-bounds read. This bug only affects Firefox on Windows. Other operating systems are unaffected. References Bug 1706501 #CVE-2021-29959: Devices could be re-enabled without additional permission prompt Reporter Jan-Ivar Bruaroey Impact low Description When a user has already allowed a website to access microphone and camera, disabling camera sharing would not fully prevent the website from re-enabling it without an additional prompt. This was only possible if the website kept recording with the microphone until re-enabling the camera. References Bug 1395819 #CVE-2021-29962: No rate-limiting for popups on Firefox for Android Reporter Wladimir Palant working with Include Security Impact low Description Firefox for Android would become unstable and hard-to-recover when a website opened too many popups. This bug only affects Firefox for Android. Other operating systems are unaffected. References Bug 1701673 #CVE-2021-29967: Memory safety bugs fixed in Firefox 89 and Firefox ESR 78.11 Reporter Mozilla developers and community Impact high Description Mozilla developers Christian Holler, Anny Gakhokidze, Alexandru Michis, Gabriele Svelto reported memory safety bugs present in Firefox 88 and Firefox ESR 78.11. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code.
