{"id":"MGASA-2020-0303","summary":"Updated nasm packages fix security vulnerability","details":"Netwide Assembler (NASM) 2.13 has a stack-based buffer over-read in the disasm\nfunction of the disasm/disasm.c file. 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).\n","modified":"2026-04-16T00:10:28.382162978Z","published":"2020-07-31T23:25:42Z","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"],"references":[{"type":"ADVISORY","url":"https://advisories.mageia.org/MGASA-2020-0303.html"},{"type":"REPORT","url":"https://bugs.mageia.org/show_bug.cgi?id=26916"},{"type":"WEB","url":"https://lists.suse.com/pipermail/sle-security-updates/2020-July/007073.html"},{"type":"WEB","url":"https://lists.opensuse.org/opensuse-security-announce/2020-07/msg00015.html"}],"affected":[{"package":{"name":"nasm","ecosystem":"Mageia:7","purl":"pkg:rpm/mageia/nasm?arch=source&distro=mageia-7"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.14.02-1.mga7"}]}],"ecosystem_specific":{"section":"core"},"database_specific":{"source":"https://advisories.mageia.org/MGASA-2020-0303.json"}}],"schema_version":"1.7.5","credits":[{"name":"Mageia","contact":["https://wiki.mageia.org/en/Packages_Security_Team"],"type":"COORDINATOR"}]}
