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

The rfbProcessClientNormalMessage function in libvncserver/rfbserver.c in LibVNCServer 0.9.9 and earlier allows remote attackers to cause a denial of service (divide-by-zero error and server crash) via a zero value in the scaling factor in a (1) PalmVNCSetScaleFactor or (2) SetScale message.
