In versions 0.3.1 through 0.3.7, the Vyper compiler generates the wrong bytecode. Any contract that uses the `raw_call` with `revert_on_failure=False` and `max_outsize=0` receives the wrong response from `raw_call`. Depending on the memory garbage, the result can be either `True` or `False`. A patch is available and, as of time of publication, anticipated to be part of Vyper 0.3.8. As a workaround, one may always put  `max_outsize>0`."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"HIGH","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-670"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:vyperlang:vyper:*:*:*:*:*:*:*:*","versionStartIncluding":"0.3.1","versionEndExcluding":"0.3.8","matchCriteriaId":"BA2EC8D5-7723-4112-B674-AB70975FDEEA"}]}]}],"references":[{"url":"https://docs.vyperlang.org/en/v0.3.7/built-in-functions.html#raw_call","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/lidofinance/gate-seals/blob/051593e74df01a4131c485b4fda52e691cd4b7d8/contracts/GateSeal.vy#L164","source":"security-advisories@github.com","tags":["Product"]},{"url":"https://github.com/lidofinance/gate-seals/pull/5/files","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/vyperlang/vyper/commit/851f7a1b3aa2a36fd041e3d0ed38f9355a58c8ae","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/vyperlang/vyper/security/advisories/GHSA-w9g2-3w7p-72g9","source":"security-advisories@github.com","tags":["Exploit","Vendor Advisory"]},{"url":"https://docs.vyperlang.org/en/v0.3.7/built-in-functions.html#raw_call","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Product"]},{"url":"https://github.com/lidofinance/gate-seals/blob/051593e74df01a4131c485b4fda52e691cd4b7d8/contracts/GateSeal.vy#L164","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Product"]},{"url":"https://github.com/lidofinance/gate-seals/pull/5/files","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/vyperlang/vyper/commit/851f7a1b3aa2a36fd041e3d0ed38f9355a58c8ae","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/vyperlang/vyper/security/advisories/GHSA-w9g2-3w7p-72g9","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Exploit","Vendor Advisory"]}]}}]}
