The related heap is allocated in the token() function and freed in the detoken() function (called by pp_getline()) - it is used again at multiple positions later that could cause multiple damages. For example, it causes a corrupted double-linked list in detoken(), a double free or corruption in delete_Token(), and an out-of-bounds write in detoken(). It has a high possibility to lead to a remote code execution attack.","severity":{"version":"3.0","score":7.8,"vector":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","level":"high","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-07","score":0.02946,"percentile":0.87234,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-416"],"published":"2017-06-29T00:00:00Z","modified":"2026-10-24T10:30:28Z","fixes":[{"ecosystem":"Debian:12","package":"nasm","fixed_in":["2.13.02-0.1"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"nasm","fixed_in":["2.13.02-0.1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"nasm","fixed_in":["2.13.02-0.1"],"sources":["osv"]},{"ecosystem":"SUSE:Linux
