Alpine: multiple nbd packages: security update to 3.24-r0

critical Tenable Self-Hosted Container Security Plugin ID 405687

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - 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 NBD_OPT_INFO,
 NBD_OPT_GO, and NBD_OPT_EXPORT_NAME messages. (CVE-2022-26495)

 - 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 NBD_OPT_INFO or NBD_OPT_GO message with an
 large value as the length of the name. (CVE-2022-26496)
