{"id":"CVE-2022-1240","summary":"Heap buffer overflow in libr/bin/format/mach0/mach0.c in radareorg/radare2","details":"Heap buffer overflow in libr/bin/format/mach0/mach0.c in GitHub repository radareorg/radare2 prior to 5.8.6. If address sanitizer is disabled during the compiling, the program should executes into the `r_str_ncpy` function. Therefore I think it is very likely to be exploitable. For more general description of heap buffer overflow, see [CWE](https://cwe.mitre.org/data/definitions/122.html).","modified":"2026-04-12T09:22:08.811341Z","published":"2022-04-06T10:15:15Z","related":["openSUSE-SU-2024:12173-1"],"database_specific":{"cna_assigner":"@huntrdev","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/1xxx/CVE-2022-1240.json","cwe_ids":["CWE-122"]},"references":[{"type":"WEB","url":"https://huntr.dev/bounties/e589bd97-4c74-4e79-93b5-0951a281facc"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/1xxx/CVE-2022-1240.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-1240"},{"type":"FIX","url":"https://github.com/radareorg/radare2/commit/ca8d8b39f3e34a4fd943270330b80f1148129de4"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/radare/radare2","events":[{"introduced":"0"},{"last_affected":"50b8813f1df7fbae3bbcb0e8d04397cd353d4759"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"5.6.6"}]}}],"versions":["0.10.0","0.10.1","0.10.2","0.10.3","0.10.4","0.10.4-termux4","0.10.5","0.10.6","0.8.6","0.8.8","0.9","0.9.2","0.9.4","0.9.6","0.9.7","0.9.8","0.9.8-rc1","0.9.8-rc2","0.9.8-rc3","0.9.8-rc4","0.9.9","1.0","1.0.0","1.0.1","1.0.2","1.1.0","1.2.0","1.2.0-git","1.3.0","1.3.0-git","1.4.0","1.5.0","1.6.0","2.0.0","2.0.1","2.1.0","2.2.0","2.4.0","2.5.0","2.6.0","2.6.9","2.7.0","2.8.0","2.9.0","3.0.0","3.0.1","3.1.0","3.1.1","3.1.2","3.1.3","3.2.0","3.2.1","3.3.0","3.4.0","3.4.1","3.5.0","3.5.1","3.6.0","3.7.0","3.7.1","3.8.0","3.9.0","4.0.0","4.1.0","4.1.1","4.2.0","4.2.1","4.3.0","4.3.1","4.4.0","4.5.1","5.0.0","5.1.0","5.1.1","5.2.0","5.2.1","5.3.0","5.3.1","5.4.0","5.4.0-git","5.4.2","5.5.0","5.5.2","5.5.4","5.6.0","5.6.2","5.6.4","5.6.6","Continuous-Windows","continuous","radare2-windows-nightly","release-5.0.0","termux"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-1240.json"}},{"ranges":[{"type":"GIT","repo":"https://github.com/radareorg/radare2","events":[{"introduced":"0"},{"fixed":"3c9ad151adf52658d814f56b9bb80bc9231da36b"}]}],"versions":["0.10.0","0.10.1","0.10.2","0.10.3","0.10.4","0.10.4-termux4","0.10.5","0.10.6","0.8.6","0.8.8","0.9","0.9.2","0.9.4","0.9.6","0.9.7","0.9.8","0.9.8-rc1","0.9.8-rc2","0.9.8-rc3","0.9.8-rc4","0.9.9","1.0","1.0.0","1.0.1","1.0.2","1.1.0","1.2.0","1.2.0-git","1.3.0","1.3.0-git","1.4.0","1.5.0","1.6.0","2.0.0","2.0.1","2.1.0","2.2.0","2.4.0","2.5.0","2.6.0","2.6.9","2.7.0","2.8.0","2.9.0","3.0.0","3.0.1","3.1.0","3.1.1","3.1.2","3.1.3","3.2.0","3.2.1","3.3.0","3.4.0","3.4.1","3.5.0","3.5.1","3.6.0","3.7.0","3.7.1","3.8.0","3.9.0","4.0.0","4.1.0","4.1.1","4.2.0","4.2.1","4.3.0","4.3.1","4.4.0","4.5.1","5.0.0","5.1.0","5.1.1","5.2.0","5.2.1","5.3.0","5.3.1","5.4.0","5.4.0-git","5.4.2","5.5.0","5.5.2","5.5.4","5.6.0","5.6.2","5.6.4","5.6.6","5.6.8","5.7.0","5.7.2","5.7.4","5.7.6","5.7.8","5.8.0","5.8.2","5.8.4","Continuous-Windows","continuous","radare2-windows-nightly","release-5.0.0","termux","wip"],"database_specific":{"vanir_signatures_modified":"2026-04-12T09:22:08Z","vanir_signatures":[{"signature_type":"Function","id":"CVE-2022-1240-b84373c8","signature_version":"v1","deprecated":false,"target":{"function":"r2pm_setenv","file":"libr/main/r2pm.c"},"digest":{"function_hash":"145063074460943694343881143365853227954","length":2497},"source":"https://github.com/radareorg/radare2/commit/3c9ad151adf52658d814f56b9bb80bc9231da36b"},{"signature_type":"Line","id":"CVE-2022-1240-d50b7e62","signature_version":"v1","deprecated":false,"target":{"file":"libr/main/r2pm.c"},"digest":{"line_hashes":["174233268195547535776550818523348433867","110857393716508268641351500537619892142","256171613986678726198978827673555401355","39846773422299067065457741506509880629","241005996178148118483357125520551727138","7345371084092435429530051306604400430","93665153460321992513043392253670786010","107126595801987420493534474550200559584"],"threshold":0.9},"source":"https://github.com/radareorg/radare2/commit/3c9ad151adf52658d814f56b9bb80bc9231da36b"}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-1240.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:H"}]}
