"Multiple vulnerabilities has been found and corrected in vino :

The rfbSendFramebufferUpdate function in
server/libvncserver/rfbserver.c in vino-server in Vino 2.x before
2.28.3, 2.32.x before 2.32.2, 3.0.x before 3.0.2, and 3.1.x before
3.1.1, when raw encoding is used, allows remote authenticated users to
cause a denial of service (daemon crash) via a large (1) X position or
(2) Y position value in a framebuffer update request that triggers an
out-of-bounds memory access, related to the rfbTranslateNone and
rfbSendRectEncodingRaw functions (CVE-2011-0904).

The rfbSendFramebufferUpdate function in
server/libvncserver/rfbserver.c in vino-server in Vino 2.x before
2.28.3, 2.32.x before 2.32.2, 3.0.x before 3.0.2, and 3.1.x before
3.1.1, when tight encoding is used, allows remote authenticated users
to cause a denial of service (daemon crash) via crafted dimensions in
a framebuffer update request that triggers an out-of-bounds read
operation (CVE-2011-0905).

The updated packages have been upgraded to 2.28.3 which is not
vulnerable to these isssues."
