1.183.1. RHBA-2011:0216: vnc bug fix update
Updated vnc packages that fix two bugs are now available for Red Hat Enterprise Linux 5.
Virtual Network Computing (VNC) is a remote display system which allows you to view a computing "desktop" environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures.
* Prior to this update, the Xvnc server could refuse a connection when it received the SIGALRM signal during the reading of a password file. With this update, the underlying source code has been modified to address this issue, and receiving the SIGALRM signal no longer prevents clients from establishing a connection. (BZ#670249
* On a system with more than 256 network interfaces, Xvnc terminated unexpectedly during startup. This error has been fixed, and Xvnc no longer crashes on systems with a large number of network interfaces. (BZ#673976
All users of vnc are advised to upgrade to these updated packages, which resolve these issues.
