RLSA-2025:9328 Important: libblockdev security update

The libblockdev packages provide a C library with GObject introspection support used for low-level operations on block devices. The library serves as a thin wrapper around plug-ins for specific functionality, such as LVM, Btrfs, LUKS, or MD RAID. Security Fixes: libblockdev: LPE from allowactive ...

A flaw was found in nbdkit due to to improperly caching plaintext state across the STARTTLS encryption boundary. A MitM attacker could use this flaw to inject a plaintext NBD_OPT_STRUCTURED_REPLY before proxying everything else a client sends to the server, potentially leading the client to terminate the NBD session. The highest threat from this vulnerability is to system availability.

CVE-2023-53513

The CVE-2023-53513 issue is a Linux kernel vulnerability where incomplete validation of the nbd ioctl arg can trigger an i_size overflow when the arg is coerced to int (arg cast in nbd_ioctl /nbd_add_socket). The root cause is insufficient validation of large ioctl arguments, allowing an overflow...
