Publication date: 20 Oct 2020
URL: https://advisories.mageia.org/MGASA-2020-0388.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-26117

Description:
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. (CVE-2020-26117)
