CVE-ID : CVE-2021-36367
Package : putty
Type : content spoofing
Remote : Yes
Link : https://security.archlinux.org/AVG-2143
The package putty before version 0.76-1 is vulnerable to content
spoofing.
Upgrade to 0.76-1.
The problem has been fixed upstream in version 0.76.
None.
PuTTY before version 0.76 proceeds with establishing an SSH session
even if it has never sent a substantive authentication response. This
makes it easier for an attacker-controlled SSH server to present a
later spoofed authentication prompt (that the attacker can use to
capture credential data, and use that data for purposes that are
undesired by the client user).
A remote SSH server could present a spoofed authentication prompt.
