Description

This security bulletin contains information about 1 vulnerability.

1) Input validation error (CVE-ID: CVE-2019-12278)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: 5.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N]

The vulnerability allows a remote non-authenticated attacker to manipulate data.

Opera through 53 on Android allows Address Bar Spoofing. Characters from several languages are displayed in Right-to-Left order, due to mishandling of several Unicode characters. The rendering mechanism, in conjunction with the "first strong character" concept, may improperly operate on a numerical IP address or an alphabetic string, leading to a spoofed URL.

Remediation

Install update from vendor's website.
