A specially crafted document can allow an attacker to pass an untrusted value as a length to a constructor. This constructor will miscalculate a length and then use it to calculate the position to write a null byte. This can allow an attacker to corrupt memory, which can result in code execution under the context of the application. An attacker must convince a victim to open a specially crafted document in order to trigger this vulnerability.","severity":{"version":"3.0","score":8.8,"vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-08","score":0.01279,"percentile":0.70181,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-123","CWE-131"],"published":"2018-12-01T18:00:00Z","modified":"2026-06-17T01:58:16Z","products":[{"vendor":"atlantiswordprocessor","product":"atlantis_word_processor"},{"vendor":"talos","product":"atlantis word processor"}],"references":[{"url":"https://talosintelligence.com/vulnerability_reports/TALOS-2018-0711","tags":["x_refsource_MISC","x_transferred","Exploit","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-4038"},{"url":"https://github.com/advisories/GHSA-g3f8-q8cx-jm7w"}],"sources":{"cve":[{"id":"CVE-2018-4038","description":"An exploitable arbitrary write vulnerability exists in the open document format parser of the Atlantis Word Processor, version 3.2.7.2, while trying to null-terminate a string.
