{"schema":"threatline.record/2","record":{"id":"CVE-2026-95520","aliases":[],"summary":"Rpm: rpm: integer overflow in iterreadarchivenext() leads to heap-based buffer overflow when parsing untrusted rpm packages","details":"A heap-based buffer overflow flaw was found in rpm. Parsing a symlink entry in an untrusted RPM package whose declared RPMTAG_LONGFILESIZES value is 0xFFFFFFFFFFFFFFFF causes an integer overflow in iterReadArchiveNext() that shrinks a buffer allocation to one byte, after which the payload's independently-controlled cpio filesize field is used to write attacker-controlled data past the end of that allocation. This is reachable via rpm2cpio, rpm2archive, and rpm -qlvp on an  untrusted package.","categories":["Operating systems"],"product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95520","source_modified_at":"2026-09-29T13:19:42.202Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 10","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95520","source_modified_at":"2026-09-29T13:19:42.202Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 6","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95520","source_modified_at":"2026-09-29T13:19:42.202Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 7","vendor":"Red Hat","versions":[],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95520","source_modified_at":"2026-09-29T13:19:42.202Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 8","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95520","source_modified_at":"2026-09-29T13:19:42.202Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Enterprise Linux 9","vendor":"Red Hat","versions":[],"defaultStatus":"affected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-95520","source_modified_at":"2026-09-29T13:19:42.202Z","fetched_at":"2026-10-23T18:52:38.922436Z","product":"Red Hat Hardened Images","vendor":"Red Hat","versions":[],"defaultStatus":"affected"}],"fixed_versions":[],"cvss":7.1,"severity":"High","kev":{"listed":false},"epss":{"probability":0.00119,"percentile":0.01697,"score_date":"2026-10-23"},"published_at":"2026-09-29T11:02:06.457Z","modified_at":"2026-09-29T13:19:42.202Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-95520","fetched_at":"2026-10-23T18:52:38.922436Z","source_modified_at":"2026-09-29T13:19:42.202Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-95520","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://access.redhat.com/security/cve/CVE-2026-95520","tags":["vdb-entry","x_refsource_REDHAT"]},{"source":"CVE List","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2537809","tags":["issue-tracking","x_refsource_REDHAT"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-09-29T13:17:45.627559Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-09-29T13:19:42.202Z","content_hash":"86222d3c7ba20360d6ad2bb4bfee281dfe7c90fcabca8adb24ed55dc95fbd5e3"}}
