An attacker can exploit this vulnerability by providing a specially crafted file containing uncompressed Rich Text Format (RTF) data. Because the application fails to properly validate input buffer boundaries before copying data in get_rtf_data_from_buf(), reading beyond the allocated memory occurs. This flaw can cause the application to crash, leading to a Denial of Service (DoS), or leak sensitive memory contents into extracted output files.","cvssScore":5.4,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","cwes":["CWE-125"],"vendors":["tnef project"],"products":["tnef"],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-103678","tags":["Third Party Advisory"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2544476","tags":["Issue Tracking","Third Party Advisory"]},{"url":"https://github.com/verdammelt/tnef","tags":["Product"]}],"exploitRefs":[{"url":"https://github.com/verdammelt/tnef","tags":["Product"]}],"hasPoc":true,"ai":null}
