Problem Description:

Multile 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
