Vulnerability from github – Published: 2023-09-28 15:30 – Updated: 2024-04-30 15:30

Details

A flaw was found in libnbd. A server can reply with a block size larger than 2^63 (the NBD spec states the size is a 64-bit unsigned value). This issue could lead to an application crash or other unintended behavior for NBD clients that doesn't treat the return value of the nbd_get_size() function correctly.

Severity ?

5.3 (Medium)
