Name of the Vulnerable Software and Affected Versions alqo versions prior to 4.1

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 versions prior to 4.1, as a temporary workaround, consider restricting the storage of invalid headers or blocks to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this issue.
