MiracleLinux 7 : tigervnc-1.3.1-3.el7 (AXSA:2015-910:01)

critical Nessus Plugin ID 291553

Synopsis

The remote MiracleLinux host is missing one or more security updates.

Description

The remote MiracleLinux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2015-910:01 advisory.

 Virtual Network Computing (VNC) is a remote display system which allows you to view a computing 'desktop' environment not only on the machine where it is running, but from anywhere on the Internet and from a wide variety of machine architectures. This package contains a client which will allow you to connect to other desktops running a VNC server.
 Security issues fixed with this release:
 CVE-2014-8240 Integer overflow in TigerVNC allows remote VNC servers to cause a denial of service (crash) and possibly execute arbitrary code via vectors related to screen size handling, which triggers a heap-based buffer overflow, a similar issue to CVE-2014-6051.
 CVE-2014-8241
 ** RESERVED ** This candidate has been reserved by an organization or individual that will use it when announcing a new security problem. When the candidate has been publicized, the details for this candidate will be provided.
 Fixed bugs:
 * The position of the mouse cursor in the VNC session was not correctly communicated to the VNC viewer, resulting in cursor misplacement. The method of displaying the remote cursor has been changed, and cursor movements on the VNC server are now accurately reflected on the VNC client.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
