EulerOS 2.0 SP2 : libvncsever (EulerOS-SA-2017-1130)

High Nessus Plugin ID 101314


The remote EulerOS host is missing a security update.


According to the version of the libvncsever package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

- Heap-based buffer overflow in rfbproto.c in LibVNCClient in LibVNCServer before 0.9.11 allows remote servers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted FramebufferUpdate message containing a subrectangle outside of the client drawing area.(CVE-2016-9941)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libvncsever package.
