4) Race condition

EUVDB-ID: #VU24059

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-17021

CWE-ID: CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to a race condition that occurs during the initialization of a new content process. A remote attacker can exploit the race to gain access to potentially sensitive information, such as heap addresses from the parent process.

Note, this vulnerability affects Windows users only.

Mitigation

Update the affected packages.

5) Cross-site scripting

EUVDB-ID: #VU24060

Risk: Medium

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-17022

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data within the CSS sanitizer. When pasting a tag from the clipboard into a rich text editor, the CSS sanitizer does not escape < and > characters. If a webpage subsequently copies the node's innerHTML, assigning it to another innerHTML, this would result in an XSS vulnerability.

Mitigation

Update the affected packages.
