A buffer overflow in TigerVNC might allow remote attackers to execute arbitrary code.
|Package||net-misc/tigervnc on all architectures|
|Affected versions||< 1.7.1|
|Unaffected versions||>= 1.7.1|
TigerVNC is a high-performance VNC server/client.
A buffer overflow vulnerability in ModifiablePixelBuffer::fillRect in vncviewer was found.
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-1.7.1"
