CVE-2005-3534

High
Published: Translated: NVD NIST

Summary

Buffer overflow vulnerability in the Network Block Device (nbd) server versions 2.7.5 and earlier, and 2.8.0 through 2.8.2. A remote attacker can send an oversized request that is written past the end of the buffer because nbd does not account for memory taken by the reply header, allowing arbitrary code execution.

Risk Assessment

The risk for the organization is the possibility of remote unauthenticated attackers taking control of the nbd server, potentially compromising the confidentiality, integrity, and availability of data stored on block devices shared by the server.

Recommendation

It is recommended to immediately upgrade the nbd server to version 2.8.3 or later, which includes a fix for the vulnerability. If an upgrade is not possible, restrict access to the nbd server to trusted networks only or apply firewall rules to block unauthorized connections.
