{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/83800?format=json","vulnerability_id":"VCID-wstr-vry1-yqbz","summary":"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.","aliases":[{"alias":"CVE-2026-22189"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-22189","reference_id":"","reference_type":"","scores":[{"value":"0.00111","scoring_system":"epss","scoring_elements":"0.29345","published_at":"2026-06-12T12:55:00Z"},{"value":"0.00111","scoring_system":"epss","scoring_elements":"0.29355","published_at":"2026-06-14T12:55:00Z"},{"value":"0.00111","scoring_system":"epss","scoring_elements":"0.29368","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00111","scoring_system":"epss","scoring_elements":"0.29145","published_at":"2026-06-11T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-22189"},{"reference_url":"https://seclists.org/fulldisclosure/2026/Jan/10","reference_id":"10","reference_type":"","scores":[{"value":"6.9","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-01-07T21:21:11Z/"}],"url":"https://seclists.org/fulldisclosure/2026/Jan/10"},{"reference_url":"https://github.com/panda3d/panda3d","reference_id":"panda3d","reference_type":"","scores":[{"value":"6.9","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-01-07T21:21:11Z/"}],"url":"https://github.com/panda3d/panda3d"},{"reference_url":"https://www.vulncheck.com/advisories/panda3d-egg-mkfont-stack-buffer-overflow","reference_id":"panda3d-egg-mkfont-stack-buffer-overflow","reference_type":"","scores":[{"value":"6.9","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-01-07T21:21:11Z/"}],"url":"https://www.vulncheck.com/advisories/panda3d-egg-mkfont-stack-buffer-overflow"},{"reference_url":"https://www.panda3d.org/","reference_id":"www.panda3d.org","reference_type":"","scores":[{"value":"6.9","scoring_system":"cvssv4","scoring_elements":"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"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:P/A:N/T:P/P:M/B:A/M:M/D:T/2026-01-07T21:21:11Z/"}],"url":"https://www.panda3d.org/"}],"weaknesses":[{"cwe_id":121,"name":"Stack-based Buffer Overflow","description":"A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function)."}],"exploits":[],"severity_range_score":"6.9 - 6.9","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-wstr-vry1-yqbz"}
