SUSE CVE-2011-0905

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...

Important: qemu

Issue Overview: A memory leakage flaw was found in the way the VNC display driver of QEMU handled the connection disconnect when ZRLE and Tight encoding are enabled. Two VncState objects are created, and one allocates memory for the Zlib's data object. This allocated memory is not freed upon...
