Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
EUVDB-ID: #VU59662
Risk: High
CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-45085
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.
The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via an "about: page" URL. A remote attacker can permanently store and execute arbitrary JavaScript code on the affected system, when the victim opens the Most Visited list tab (ephy-about:overview) in browser.
Install updates from vendor's repository.
