USN-5361-1 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities

It was discovered that the VFIO PCI driver in the Linux kernel did not properly handle attempts to access disabled memory spaces. A local attacker could use this to cause a denial of service system crash. CVE-2020-12888 Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation did not...

nbd integer overflow Code Execution

The vulnerability of NBD network block devices is related to integer overflows. Exploiting this vulnerability allows a malicious actor to execute arbitrary code by sending specially crafted messages such as NBDOPTINFO, NBDOPTGO, and NBDOPTEXPORTNAME...

nbd Buffer Overflow Code Execution

The vulnerability of nbd network block devices relates to buffer overflow in the stack. Exploiting this vulnerability allows a remote attacker to execute arbitrary code by sending specially crafted data...

ROS-20220329-04

Vulnerability in nbd network block device implementation, related to stack-based buffer overflow during NBDOPTINFO or NBDOPTGO messages. Exploitation of the vulnerability could allow an attacker, acting remotely and not authenticated, to pass specially crafted data to an application, causing a...

libnbd: nbdcopy: missing error handling may create corrupted destination image

A flaw was found in the copying tool nbdcopy of libnbd. When performing multi-threaded copies using asynchronous nbd calls, nbdcopy was blindly treating the completion of an asynchronous command as successful, rather than checking the error parameter. This could result in the silent creation of a...

USN-5323-1 nbd vulnerabilities

It was discovered that NBD incorrectly handled name length fields. A remote attacker could use this issue to cause NBD to crash, resulting in a denial of service, or possibly execute arbitrary code...

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...

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,...

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...

UBUNTU-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...

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...
