{"id":"DEBIAN-CVE-2019-12760","details":"A deserialization vulnerability exists in the way parso through 0.4.0 handles grammar parsing from the cache. Cache loading relies on pickle and, provided that an evil pickle can be written to a cache grammar file and that its parsing can be triggered, this flaw leads to Arbitrary Code Execution. NOTE: This is disputed because \"the cache directory is not under control of the attacker in any common configuration.","modified":"2026-09-21T07:01:49.434578522Z","published":"2019-06-06T19:29:00.500Z","upstream":["CVE-2019-12760"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2019-12760"}],"affected":[{"package":{"name":"parso","ecosystem":"Debian:12","purl":"pkg:deb/debian/parso?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.5.1-0.1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2019-12760.json"}},{"package":{"name":"parso","ecosystem":"Debian:13","purl":"pkg:deb/debian/parso?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.5.1-0.1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2019-12760.json"}},{"package":{"name":"parso","ecosystem":"Debian:14","purl":"pkg:deb/debian/parso?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.5.1-0.1"}]}],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2019-12760.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
