Base vector

AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H

Name of the Vulnerable Software and Affected Versions Peercoin versions through 0.6.4

Description The issue allows a remote denial of service, which can be exploited by an attacker who acquires a small amount of stake or coins in the system. The attacker can send invalid headers or blocks, which are then stored on the victim's disk.

Recommendations For Peercoin versions through 0.6.4, consider restricting the storage of invalid headers or blocks to prevent disk space exhaustion until a patch is available. As a temporary workaround, implement measures to limit the impact of invalid data on the system, such as filtering out suspicious transactions or temporarily disabling the processing of new blocks.
