Name of the Vulnerable Software and Affected Versions: evm versions prior to 0.21.1 evm versions prior to 0.23.1 evm versions prior to 0.24.1 evm versions prior to 0.25.1 evm versions prior to 0.26.1

Description: The issue is related to the execution of specific EVM opcodes that use evm core::Memory::copy large for memory operations, which can lead to over-allocation of memory when not needed. This makes it possible for an attacker to perform a denial-of-service attack.

Recommendations: For evm versions prior to 0.21.1, upgrade to version 0.21.1. For evm versions prior to 0.23.1, upgrade to version 0.23.1. For evm versions prior to 0.24.1, upgrade to version 0.24.1. For evm versions prior to 0.25.1, upgrade to version 0.25.1. For evm versions prior to 0.26.1, upgrade to version 0.26.1 or later.
