nbd buffer overflow vulnerability

nbd is a Linux kernel network block device tool. It is used to use remote block devices over TCP/IP networks. nbd versions prior to 3.24 of nbd-server suffer from a buffer overflow vulnerability that can be exploited by an attacker to cause a parsing buffer overflow in the name field by sending a...

nbd input validation error vulnerability

nbd is a tool for Linux kernel network block devices. It is used to use remote block devices over TCP/IP networks. nbd versions prior to 3.24 have an input validation error vulnerability in nbd-server, which stems from an integer overflow in nbd-server, resulting in a heap-based buffer overflow...

DEBIAN-CVE-2022-26496

In nbd-server in nbd before 3.24, there is a stack-based buffer overflow. An attacker can cause a buffer overflow in the parsing of the name field by sending a crafted NBDOPTINFO or NBDOPTGO message with an large value as the length of the name...

CVE-2022-26495

In nbd-server in nbd before 3.24, there is an integer overflow with a resultant heap-based buffer overflow. A value of 0xffffffff in the name length field will cause a zero-sized buffer to be allocated for the name, resulting in a write to a dangling pointer. This issue exists for the NBDOPTINFO,...

The vulnerability of the Network Block Device (NBD) emulator’s hardware emulation software, QEMU, stems from improper resource management by external emulators. This allows a malicious actor to trigger a service failure.

The vulnerability of the Network Block Device NBD emulation software from QEMU lies in the sending of a request by the client, which corresponds to a specification that is located within the maximum allowable range of request length. Exploiting this vulnerability allows an attacker who operates...
