		<Note Title="Description" Type="General" Ordinal="3" xml:lang="en">NASM is the Netwide Assembler, a free portable assembler for the Intel 80x86 microprocessor series, using primarily the traditional Intel instruction mnemonics and syntax. It also provides tools in RDOFF binary format, includes linker, library manager, loader, and information dump.\r\n\r\n
Security Fix(es):\r\n\r\n
In Netwide Assembler (NASM) 2.15rc0, a heap-based buffer over-read occurs (via a crafted .asm file) in set_text_free when called from expand_one_smacro in asm/preproc.c.(CVE-2019-20352)\r\n\r\n
In Netwide Assembler (NASM) 2.15rc10, there is heap use-after-free in saa_wbytes in nasmlib/saa.c.(CVE-2020-24241)\r\n\r\n</Note>
		<Note Title="Topic" Type="General" Ordinal="4" xml:lang="en">An update for nasm is now available for openEuler-20.03-LTS and openEuler-20.03-LTS-SP1.\r\n\r\n
openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.</Note>
