A NULL pointer dereference flaw was found in the way LibVNCServer handled certain ClientCutText message. A remote attacker could use this flaw to crash the VNC server by sending a specially crafted ClientCutText message from a VNC client. (CVE-2014-6053)
A divide-by-zero flaw was found in the way LibVNCServer handled the scaling factor when it was set to ‘0’. A remote attacker could use this flaw to crash the VNC server using a malicious VNC client.
(CVE-2014-6054)
Two stack-based buffer overflow flaws were found in the way LibVNCServer handled file transfers. A remote attacker could use this flaw to crash the VNC server using a malicious VNC client.
(CVE-2014-6055)
Note: Prior to this update, the kdenetwork packages used an embedded copy of the LibVNCServer library. With this update, the kdenetwork packages have been modified to use the system LibVNCServer packages.
Therefore, the update provided by SLSA-2014:1826 must be installed to fully address the issues in krfb described above.
All running instances of the krfb server must be restarted for this update to take effect.
