CVE-2020-26117

In rfb/CSecurityTLS.cxx and rfb/CSecurityTLS.java in TigerVNC before 1.11.0, viewers mishandle TLS certificate exceptions. They store the certificates as authorities, meaning that the owner of a certificate could impersonate any server after a client had added an exception.

Severity: MEDIUM (5.8) Vector: AV:N/AC:M/Au:N/C:P/I:P/A:N
Severity: HIGH (8.1) Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:N
