TigerVNC is a high-performance VNC server/client.
Two boundary errors in TigerVNC could lead to a heap-based buffer overflow.
A remote attacker could entice a user to connect to a malicious VNC server using TigerVNC, possibly resulting in execution of arbitrary code with the privileges of the process or 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-1.3.1"
