It was discovered that Dovecot before versions 2.2.36.1 and 2.3.4.1 incorrectly handled client certificates. A remote attacker in possession of a valid certificate with an empty username field could possibly use this issue to impersonate other users.
Products | Ubuntu_linux, Dovecot, Leap |
Type | Improper Certificate Validation (CWE-295) |
First patch | - None (likely due to unavailable code) |
