{"id":"CVE-2026-22189","state":"PUBLISHED","title":"Panda3D <= 1.10.16 egg-mkfont Stack Buffer Overflow","description":"The egg-mkfont utility in Panda3D versions up to and including 1.10.16 contains a stack-based buffer overflow vulnerability due to use of an unbounded sprintf() call with attacker-controlled input. When constructing glyph filenames, egg-mkfont formats a user-supplied glyph pattern (-gp) into a fixed-size stack buffer without length validation. Supplying an excessively long glyph pattern string can overflow the stack buffer, resulting in memory corruption and a deterministic crash. Depending on build configuration and execution environment, the overflow may also be exploitable for arbitrary code execution.","publishedAt":"2026-01-07T20:25:37.702Z","updatedAt":"2026-07-14T15:53:11.566Z","severity":{"score":6.9,"label":"Medium","version":"4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"VulnCheck"},"assigner":"VulnCheck","products":["Panda3D Panda3D"],"affected":[{"vendor":"Panda3D","product":"Panda3D","packageURL":"pkg:github/panda3d/panda3d","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"1.10.16","versionType":"semver"}],"repo":"https://github.com/panda3d/panda3d"}],"references":["https://seclists.org/fulldisclosure/2026/Jan/10","https://www.panda3d.org/","https://github.com/panda3d/panda3d","https://www.vulncheck.com/advisories/panda3d-egg-mkfont-stack-buffer-overflow"],"weaknesses":["CWE-121"],"ingestedAt":"2026-10-29T20:11:21.040Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/22xxx/CVE-2026-22189.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-22189","state":"PUBLISHED","datePublished":"2026-01-07T20:25:37.702Z","dateUpdated":"2026-07-14T15:53:11.566Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-01-06T16:47:17.183Z"},"containers":{"cna":{"title":"Panda3D <= 1.10.16 egg-mkfont Stack Buffer Overflow","descriptions":[{"lang":"en","value":"The egg-mkfont utility in Panda3D versions up to and including 1.10.16 contains a stack-based buffer overflow vulnerability due to use of an unbounded sprintf() call with attacker-controlled input.
