{"id":"UBUNTU-CVE-2026-111144","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":"2026-10-17T12:58:03.897833613Z","published":"2026-10-16T00:00:00Z","upstream":["CVE-2026-111144"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-111144"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-111144"},{"type":"REPORT","url":"https://github.com/ansilove/libansilove"},{"type":"REPORT","url":"https://github.com/ansilove/libansilove/blob/f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3/src/drawchar.c#L28-L35"},{"type":"REPORT","url":"https://github.com/ansilove/libansilove/blob/f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3/src/loaders/xbin.c#L119-L166"},{"type":"REPORT","url":"https://github.com/ansilove/libansilove/blob/f1b05447aa566aa4eef9b05ebf8c2aaf1e379cd3/src/loaders/xbin.c#L224-L232"},{"type":"REPORT","url":"https://hackmd.io/@haind-pwn/libansilove-xbin-rle-oob-read-and-null-font-deref"},{"type":"REPORT","url":"https://www.vulncheck.com/advisories/libansilove-1.3.0-through-1.4.2-null-pointer-dereference-via-ansilove-xbin"}],"affected":[{"package":{"name":"libansilove","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libansilove?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.2-1","1.1.5-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libansilove1","binary_version":"1.1.5-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111144.json"}},{"package":{"name":"libansilove","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libansilove?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.2.8-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libansilove1","binary_version":"1.2.8-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111144.json"}},{"package":{"name":"libansilove","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libansilove?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.1-1","1.4.1-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"libansilove1","binary_version":"1.4.1-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111144.json"}},{"package":{"name":"libansilove","ecosystem":"Ubuntu:26.10","purl":"pkg:deb/ubuntu/libansilove?arch=source&distro=stonking"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.2-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libansilove1","binary_version":"1.4.2-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111144.json"}},{"package":{"name":"libansilove","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libansilove?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.4.1-2","1.4.2-1","1.4.2-2"],"ecosystem_specific":{"binaries":[{"binary_name":"libansilove1","binary_version":"1.4.2-2"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-111144.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"},{"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"},{"type":"Ubuntu","score":"medium"}]}
