While searching for an object identifier in a malformed document that is missing from the cross-reference table, the application will save a reference to the object’s cross-reference table entry inside a stack variable. If the referenced object identifier is not found, the application may resize the cross-reference table which can change the scope of its entry. Later when the application tries to reference cross-reference entry via the stack variable, the application will access memory belonging to the recently freed table causing a use-after-free condition. A specially crafted document can be delivered by an attacker and loaded by a victim in order to trigger this vulnerability.","publishedAt":"2020-09-17T12:19:21.000Z","updatedAt":"2024-08-04T08:47:41.116Z","severity":{"score":8.8,"label":"High","version":"3.0","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","source":"talos"},"assigner":"talos","products":["n/a Nitro Pro"],"affected":[{"vendor":"n/a","product":"Nitro Pro","versions":[{"version":"Nitro Pro 13.13.2.242 ,Nitro Pro 13.16.2.300","status":"affected"}]}],"references":["https://talosintelligence.com/vulnerability_reports/TALOS-2020-1068"],"weaknesses":["CWE-416"],"ingestedAt":"2026-10-29T19:47:38.312Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2020/6xxx/CVE-2020-6115.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2020-6115","state":"PUBLISHED","datePublished":"2020-09-17T12:19:21.000Z","dateUpdated":"2024-08-04T08:47:41.116Z","assignerShortName":"talos","assignerOrgId":"b86d76f8-0f8a-4a96-a78d-d8abfc7fc29b","dateReserved":"2020-01-07T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"An exploitable vulnerability exists in the cross-reference table repairing functionality of Nitro Software, Inc.’s Nitro Pro 13.13.2.242.
