{"id":"GHSA-369h-pjr2-6wrh","summary":"Uncontrolled recursion in trust-dns-proto","details":"There's a stack overflow leading to a crash when Trust-DNS's parses a malicious DNS packet. Affected versions of this crate did not properly handle parsing of DNS message compression (RFC1035 section 4.1.4). The parser could be tricked into infinite loop when a compression offset pointed back to the same domain name to be parsed. This allows an attacker to craft a malicious DNS packet which when consumed with Trust-DNS could cause stack overflow and crash the affected software.","aliases":["CVE-2018-20994","RUSTSEC-2018-0007"],"modified":"2023-11-08T04:00:13.553878Z","published":"2021-08-25T20:43:16Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2021-08-19T21:24:41Z","nvd_published_at":null,"cwe_ids":["CWE-674"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2018-20994"},{"type":"PACKAGE","url":"https://github.com/bluejekyll/trust-dns"},{"type":"WEB","url":"https://rustsec.org/advisories/RUSTSEC-2018-0007.html"}],"affected":[{"package":{"name":"trust-dns-proto","ecosystem":"crates.io","purl":"pkg:cargo/trust-dns-proto"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.4.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2021/08/GHSA-369h-pjr2-6wrh/GHSA-369h-pjr2-6wrh.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
