Mageia: 2022-0403 Moderate: Nbd Integer Overflow And Buffer Overflow

It was discovered that nbd prior to 3.24 contained 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 (CVE-2022-26495).
Stack-based buffer overflow. An attacker can cause a buffer overflow in the parsing of the name field by sending a crafted NBD_OPT_INFO or NBD_OPT_GO message with an large value as the length of the name. (CVE-2022-26496)
Packaging has been adjusted to create the required nbd user and group at installation.
