In versions 0.3.10 and prior, using the `slice` builtin can result in a double eval vulnerability when the buffer argument is either `msg.data`, `self.code` or `<address>.code` and either the `start` or `length` arguments have side-effects. It can be easily triggered only with the versions `<0.3.4` as `0.3.4` introduced the unique symbol fence. No vulnerable production contracts were found. Additionally, double evaluation of side-effects should be easily discoverable in client tests. As such, the impact is low. As of time of publication, no fixed versions are available.\n\n"}],"source":{"advisory":"GHSA-r56x-j438-vw5m","discovery":"UNKNOWN"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-32646","role":"CISA Coordinator","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-04-30T16:05:58.539270Z"}}}],"affected":[{"cpes":["cpe:2.3:a:vyperlang:vyper:*:*:*:*:*:*:*:*"],"vendor":"vyperlang","product":"vyper","versions":[{"status":"affected","version":"*"}],"defaultStatus":"unknown"}],"providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-04T17:49:53.303Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T02:13:40.232Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/vyperlang/vyper/security/advisories/GHSA-r56x-j438-vw5m","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/vyperlang/vyper/security/advisories/GHSA-r56x-j438-vw5m"}]}]}}
