Prior to the patch, when executing specific EVM opcodes related to memory operations that use evm_core::Memory::copy_large
, the crate can over-allocate memory when it is not needed, making it possible for an attacker to perform denial-of-service attack.
The flaw was corrected in commit 19ade85
. Users should upgrade to ==0.21.1, ==0.23.1, ==0.24.1, ==0.25.1, >=0.26.1
.
None. Please upgrade your evm
crate version
