SUSE update for MozillaFirefox

1) Improperly implemented security check for standard

EUVDB-ID: #VU50881

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-23968

CWE-ID: CWE-358 - Improperly Implemented Security Check for Standard

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to incorrect implementation of W3C Content Security Policy. If Content Security Policy blocked frame navigation, the full destination of a redirect served in the frame was reported in the violation report; as opposed to the original frame URI. A remote attacker can gain knowledge of sensitive information contained in such URIs.

Mitigation

Update the affected package MozillaFirefox to the latest version.
