{"id":"CVE-2026-111143","summary":"Ansilove libansilove through 1.4.2 Out-of-Bounds Read via ansilove_xbin RLE Decoding","details":"Ansilove libansilove through 1.4.2 contains an out-of-bounds read vulnerability in ansilove_xbin() in src/loaders/xbin.c that lacks bounds checks for compressed run-length records. Attackers can supply a crafted compressed XBIN file ending in a control byte such as 0x7F to read past the input buffer, crashing applications that render untrusted XBIN art.","modified":"2026-10-17T02:46:44.115950686Z","published":"2026-10-15T18:57:34.707Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111143.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-125"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111143.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111143"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/ansilove-libansilove-through-1.4.2-out-of-bounds-read-via-ansilove-xbin-rle-decoding"},{"type":"PACKAGE","url":"https://github.com/ansilove/libansilove"},{"type":"ARTICLE","url":"https://github.com/ansilove/libansilove/blob/f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3/src/loaders/xbin.c#L169-L241"},{"type":"EVIDENCE","url":"https://hackmd.io/@haind-pwn/libansilove-xbin-rle-oob-read-and-null-font-deref"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/ansilove/libansilove","events":[{"introduced":"0"},{"fixed":"f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"0"},{"last_affected":"1.4.2"},{"fixed":"1.4.2"}]}}],"versions":["1.4.1","1.4.0","1.3.1","1.3.0","1.2.9","1.2.8","1.2.7","1.2.6","1.2.5","1.2.4","1.2.3","1.2.2","1.2.1","1.2.0","1.1.9","1.1.8","1.1.7","1.1.6","1.1.5","1.1.4","1.1.3","1.1.2","1.1.1","1.1.0","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111143.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N"}]}
