CWE-476  (opens in a new tab)

How to fix?

Upgrade Centos:7 kdenetwork-common to version 7:4.10.5-8.el7_0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kdenetwork-common package and not the kdenetwork-common package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier does not properly handle attempts to send a large amount of ClientCutText data, which allows remote attackers to cause a denial of service (memory consumption or daemon crash) via a crafted message that is processed by using a single unchecked malloc.
