CVE-2005-3534: Wouter verhelst nbd memory buffer overflow vulnerability

WWouter Verhelst · Nbd

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.
