SUSE CVE-2005-3534

Buffer overflow in the Network Block Device nbd server 2.7.5 and earlier, and 2.8.0 through 2.8.2, allows remote attackers to execute arbitrary code via a large request, which is written past the end of the buffer because nbd does not account for memory taken by the reply header...

SUSE CVE-2008-0928

Qemu 0.9.1 and earlier does not perform range checks for block device read or write requests, which allows guest host users with root privileges to access arbitrary memory and escape the virtual machine...

SUSE CVE-2011-0530

Buffer overflow in the mainloop function in nbd-server.c in the server in Network Block Device nbd before 2.9.20 might allow remote attackers to execute arbitrary code via a long request. NOTE: this issue exists because of a CVE-2005-3534 regression...

SUSE CVE-2011-1925

nbd-server.c in Network Block Device nbd-server 2.9.21 allows remote attackers to cause a denial of service NULL pointer dereference and crash by causing a negotiation failure, as demonstrated by specifying a name for a non-existent export...

SUSE CVE-2011-4127
