Red Hat Security Advisory 2013-0169-01 - Vino is a Virtual Network Computing server for GNOME. It allows remote users to connect to a running GNOME session using VNC. It was found that Vino transmitted all clipboard activity on the system running Vino to all clients connected to port 5900, even those who had not authenticated. A remote attacker who is able to access port 5900 on a system running Vino could use this flaw to read clipboard data without authenticating. Two out-of-bounds memory read flaws were found in the way Vino processed client framebuffer requests in certain encodings. An authenticated client could use these flaws to send a specially-crafted request to Vino, causing it to crash.

762e8c4f2a7429d7a006ec98826a518cee1f681808fcb98fe4d3c053db743f00Mandriva Linux Security Advisory 2011-087 - 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 X position or Y position value in a framebuffer update request that triggers an out-of-bounds memory access, related to the rfbTranslateNone and rfbSendRectEncodingRaw functions. 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 via crafted dimensions in a framebuffer update request that triggers an out-of-bounds read operation. The updated packages have been upgraded to 2.28.3 which is not vulnerable to these issues.
