Fedora 15 : tigervnc-1.0.90-4.fc15 (2011-6838)

Medium Nessus Plugin ID 54633


The remote Fedora host is missing a security update.


This update fixes following issue :

- vncviewer could have sent user password to VNC server without proper validation of the server's X.509 certificate when secure X.509 authentication was requested (CVE-2011-1775)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected tigervnc package.
