TigerVNC: Integer overflow An integer overflow in TigerVNC might allow remote attackers to execute arbitrary code. tigervnc 2016-12-13 2016-12-13 534714 remote 1.4.2 1.4.2

TigerVNC is a high-performance VNC server/client.

TigerVNC is impacted by the same vulnerability as found in CVE-2014-6051. An integer overflow, leading to a heap-based buffer overflow, was found in the way screen sizes were handled.

A remote attacker, utilizing a malicious VNC server, could execute arbitrary code with the privileges of the user running the client, or cause a Denial of Service condition.

There is no known workaround at this time.

All TigerVNC users should upgrade to the latest version:

# emerge --sync # emerge --ask --oneshot --verbose ">=net-misc/tigervnc-1.4.2"
