CVE-2014-6053

Publication date 24 September 2014

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

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.
