Debian DLA-2146-1 : libvncserver security update

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.

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

Solution

Upgrade the affected packages.
