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"
OS | Version | Architecture | Package | Version | Filename |
