Description

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to incorrect processing of newline characters in extension's name. A remote attacker can manually add newline characters to the tag <DisplayName> under the "extension.vsixmanifest" file, which will hide information about digital signature of an unsigned extension leading to a spoofing attack.

Successful exploitation of the vulnerability will require a victim to install a malicious extension.


Remediation

Install updates from vendor's website.
