An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of GHSA-773q-5334-5gf9 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- evm-core (crates.io): affected all versions; fixed in 0.21.1\n- evm-core (crates.io): affected all versions; fixed in 0.21.1\n- evm-core (crates.io): affected from 0.0.0-0; fixed in 0.21.1, 0.23.1, 0.24.1, 0.25.1, 0.26.1\n- evm-core (crates.io): affected from 0.23.0; fixed in 0.23.1\n- evm-core (crates.io): affected from 0.23.0; fixed in 0.23.1\n- evm-core (crates.io): affected from 0.24.0; fixed in 0.24.1\n- evm-core (crates.io): affected from 0.24.0; fixed in 0.24.1\n- evm-core (crates.io): affected from 0.25.0; fixed in 0.25.1\n- evm-core (crates.io): affected from 0.25.0; fixed in 0.25.1\n- evm-core (crates.io): affected from 0.26.0; fixed in 0.26.1\n- evm-core (crates.io): affected from 0.26.0; fixed in 0.26.1\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-773q-5334-5gf9/ (Markdown: https://insights.sbomify.com/GHSA-773q-5334-5gf9/index.md)","id":"GHSA-773q-5334-5gf9","markdown":"https://insights.sbomify.com/GHSA-773q-5334-5gf9/index.md","name":"GHSA-773q-5334-5gf9","record":{"aliases":["RUSTSEC-2021-0066"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"EVM core library","requires_auth":"none","summary":"An attacker can cause denial of service by triggering memory over-allocation in the evm-core library via specific EVM opcodes.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Prior to the patch, when executing specific EVM opcodes related\nto memory operations that use `evm_core::Memory::copy_large`, the\ncrate can over-allocate memory when it is not needed, making it\npossible for an attacker to perform denial-of-service attack.\n\nThe flaw was corrected in commit `19ade85`.","ecosystems":["crates.io"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":true,"headline":"Memory over-allocation in evm-core","id":"GHSA-773q-5334-5gf9","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2021"},"n_packages":11,"n_references":null,"packages":[{"ecosystem":"crates.io","fixed":["0.21.1"],"introduced":["0"],"last_affected":[],"package":"evm-core","purl":null,"source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.21.1"],"introduced":["0"],"last_affected":[],"package":"evm-core","purl":"pkg:cargo/evm-core","source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.21.1","0.23.1","0.24.1","0.25.1","0.26.1"],"introduced":["0.0.0-0","0.22.0-0","0.24.0-0","0.25.0-0","0.26.0-0"],"last_affected":[],"package":"evm-core","purl":"pkg:cargo/evm-core","source":"RUSTSEC-2021-0066"},{"ecosystem":"crates.io","fixed":["0.23.1"],"introduced":["0.23.0"],"last_affected":[],"package":"evm-core","purl":null,"source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.23.1"],"introduced":["0.23.0"],"last_affected":[],"package":"evm-core","purl":"pkg:cargo/evm-core","source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.24.1"],"introduced":["0.24.0"],"last_affected":[],"package":"evm-core","purl":null,"source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.24.1"],"introduced":["0.24.0"],"last_affected":[],"package":"evm-core","purl":"pkg:cargo/evm-core","source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.25.1"],"introduced":["0.25.0"],"last_affected":[],"package":"evm-core","purl":null,"source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.25.1"],"introduced":["0.25.0"],"last_affected":[],"package":"evm-core","purl":"pkg:cargo/evm-core","source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.26.1"],"introduced":["0.26.0"],"last_affected":[],"package":"evm-core","purl":null,"source":"GHSA-773q-5334-5gf9"},{"ecosystem":"crates.io","fixed":["0.26.1"],"introduced":["0.26.0"],"last_affected":[],"package":"evm-core","purl":"pkg:cargo/evm-core","source":"GHSA-773q-5334-5gf9"}],"products":null,"published":"2021-05-11","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"open","licence":"CC0 1.0","name":"RustSec","prefix":"RUSTSEC"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"An attacker can cause denial of service by triggering memory over-allocation in the evm-core library via specific EVM opcodes.","url":"https://insights.sbomify.com/GHSA-773q-5334-5gf9/"}
