high Nessus Plugin ID 134633

Language:

Synopsis

The remote Debian host is missing a security update.

Description

In libvncserver, through libvncclient/cursor.c, there is a possibility of a heap overflow, as reported by Pavel Cheremushkin.

For Debian 8 'Jessie', this problem has been fixed in version 0.9.9+dfsg2-6.1+deb8u7.

We recommend that you upgrade your libvncserver packages.

Solution

Upgrade the affected packages.
