GHSA-4JWQ-572W-4388

Vulnerability from github – Published: 2024-01-30 23:55 – Updated: 2024-01-30 23:55

Summary

Memory over-allocation in evm crate

Details

Impact

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.

Patches

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.

Workarounds

None. Please upgrade your evm crate version

CVE-2021-29511 (GCVE-0-2021-29511)

Vulnerability from cvelistv5 – Published: 2021-05-12 17:15 – Updated: 2024-08-03 22:11

Summary

evm is a pure Rust implementation of Ethereum Virtual Machine. Prior to the patch, when executing specific EVM opcodes related to memory operations that use `evm_core::Memory::copy_large`, the `evm` 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`. There are no workarounds. Please upgrade your `evm` crate version.

Prior to the patch, when executing specific EVM opcodes related to memory operations that use `evm_core::Memory::copy_large`, the `evm` 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, \u003e=0.26.1`. There are no workarounds. Please upgrade your `evm` crate version."
