{"id":"CVE-2026-111144","summary":"libansilove 1.3.0 through 1.4.2 NULL Pointer Dereference via ansilove_xbin","details":"libansilove 1.3.0 through 1.4.2 contains a NULL pointer dereference vulnerability in ansilove_xbin() that allows attackers to crash applications by supplying a crafted XBIN file. Attackers can set the 512-character flag without the custom-font flag, causing drawchar() to index a NULL high_font_data_xbin pointer and terminate the process.","modified":"2026-10-17T02:48:20.220910107Z","published":"2026-10-15T18:57:35.373Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-476"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111144.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/111xxx/CVE-2026-111144.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111144"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/libansilove-1.3.0-through-1.4.2-null-pointer-dereference-via-ansilove-xbin"},{"type":"PACKAGE","url":"https://github.com/ansilove/libansilove"},{"type":"ARTICLE","url":"https://github.com/ansilove/libansilove/blob/f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3/src/drawchar.c#L28-L35"},{"type":"ARTICLE","url":"https://github.com/ansilove/libansilove/blob/f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3/src/loaders/xbin.c#L119-L166"},{"type":"ARTICLE","url":"https://github.com/ansilove/libansilove/blob/f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3/src/loaders/xbin.c#L224-L232"},{"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":"04fab9ff04d5150b963144bfff5ce608dafe1617"},{"fixed":"f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3"}],"database_specific":{"source":["AFFECTED_FIELD","DESCRIPTION"],"extracted_events":[{"introduced":"1.3.0"},{"last_affected":"1.4.2"},{"fixed":"1.4.2"}]}}],"versions":["1.4.1","1.4.0","1.3.1","1.3.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-111144.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"}]}
