Remote attackers could leverage this\nvulnerability to cause a denial of service or possibly have unspecified other\nimpact via a crafted ELF file (CVE-2018-10254).\n\nNetwide Assembler (NASM) 2.14rc0 has an endless while loop in the\nassemble_file function of asm/nasm.c because of a globallineno integer\noverflow (CVE-2018-10316).\n\nNetwide Assembler (NASM) 2.14rc15 has a buffer over-read in x86/regflags.c\n(CVE-2018-16382).\n\nNASM nasm-2.13.03 nasm- 2.14rc15 version 2.14rc15 and earlier contains a\nmemory corruption (crashed) of nasm when handling a crafted file due to\nfunction assemble_file(inname, depend_ptr) at asm/nasm.c:482. vulnerability in\nfunction assemble_file(inname, depend_ptr) at asm/nasm.c:482. that can result\nin aborting/crash nasm program. This attack appear to be exploitable via a\nspecially crafted asm file (CVE-2018-1000667).\n\nasm/labels.c in Netwide Assembler (NASM) is prone to NULL Pointer Dereference,\nwhich allows the attacker to cause a denial of service via a crafted file\n(CVE-2018-16517).\n\nNetwide Assembler (NASM) 2.14rc15 has an invalid memory write (segmentation\nfault) in expand_smacro in preproc.c, which allows attackers to cause a denial\nof service via a crafted input file (CVE-2018-16999).\n\nNetwide Assembler (NASM) 2.14rc16 has a heap-based buffer over-read in\nexpand_mmac_params in asm/preproc.c for the special cases of the % and $ and !\ncharacters (CVE-2018-19215).\n\nNetwide Assembler (NASM) 2.14rc15 has a heap-based buffer over-read in\nexpand_mmac_params in asm/preproc.c for insufficient input (CVE-2018-19214).","dates":{"published":"2020-07-31T23:25:42.000Z","modified":"2026-04-16T04:43:11.004Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"nasm","name":"nasm","label":"nasm","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/nasm","purlType":"rpm","versions":[{"text":"< 2.14.02-1.mga7","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 2.14.02-1.mga7","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://advisories.mageia.org/MGASA-2020-0303.html","label":"advisories.mageia.org/MGASA-2020-0303.html","hostname":"advisories.mageia.org","tags":["Advisory"]},{"url":"https://bugs.mageia.org/show_bug.cgi?id=26916","label":"bugs.mageia.org/show_bug.cgi?id=26916","hostname":"bugs.mageia.org","tags":["REPORT"]},{"url":"https://lists.suse.com/pipermail/sle-security-updates/2020-July/007073.html","label":"lists.suse.com/pipermail/sle-security-updates/2020-July/007073.html","hostname":"lists.suse.com","tags":["WEB"]},{"url":"https://lists.opensuse.org/opensuse-security-announce/2020-07/msg00015.html","label":"lists.opensuse.org/opensuse-security-announce/2020-07/msg00015.html","hostname":"lists.opensuse.org","tags":["WEB"]}],"lineage":{"upstream":["CVE-2018-1000667","CVE-2018-10016","CVE-2018-10254","CVE-2018-10316","CVE-2018-16382","CVE-2018-16517","CVE-2018-16999","CVE-2018-19214","CVE-2018-19215"],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2020-07-31T23:25:42.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2026-04-16T04:43:11.004Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T05:45:17.346Z","stale":false,"partial":false}}
