In Netwide Assembler (NASM) 2.14.02, there is a use-after-free in paste_tokens in asm/preproc.c.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - nasm: use-after-free in paste_tokens in asm/preproc.c (CVE-2019-8343)

  - NASM nasm-2.13.03 nasm- 2.14rc15 version 2.14rc15 and earlier contains a memory corruption (crashed) of     nasm when handling a crafted file due to function assemble_file(inname, depend_ptr) at asm/nasm.c:482.
    vulnerability in function assemble_file(inname, depend_ptr) at asm/nasm.c:482. that can result in     aborting/crash nasm program. This attack appear to be exploitable via a specially crafted asm file..
    (CVE-2018-1000667)

  - nasm version 2.14.01rc5, 2.15 contains a Buffer Overflow vulnerability in asm/stdscan.c:130 that can     result in Stack-overflow caused by triggering endless macro generation, crash the program. This attack     appear to be exploitable via a crafted nasm input file. (CVE-2018-1000886)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 6 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - nasm: use-after-free in paste_tokens in asm/preproc.c (CVE-2019-8343)

  - In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote attackers to cause a denial of service (heap-     based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
    (CVE-2017-11111)

  - In Netwide Assembler (NASM) 2.14rc0, there is an illegal address access in the function paste_tokens() in     preproc.c, aka a NULL pointer dereference. It will lead to remote denial of service. (CVE-2017-14228)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - nasm: use-after-free in paste_tokens in asm/preproc.c (CVE-2019-8343)

  - In Netwide Assembler (NASM) 2.14rc0, there are multiple heap use after free vulnerabilities in the tool     nasm. 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. (CVE-2017-10686)

  - In Netwide Assembler (NASM) 2.14rc0, preproc.c allows remote attackers to cause a denial of service (heap-     based buffer overflow and application crash) or possibly have unspecified other impact via a crafted file.
    (CVE-2017-11111)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote host is affected by the vulnerability described in GLSA-202312-09 (NASM: Multiple Vulnerabilities)

  - In Netwide Assembler (NASM) 2.14.02, there is a use-after-free in paste_tokens in asm/preproc.c.
    (CVE-2019-8343)

  - A Segmentation Fault issue discovered in in ieee_segment function in outieee.c in nasm 2.14.03 and 2.15     allows remote attackers to cause a denial of service via crafted assembly file. (CVE-2020-21528)

  - NASM v2.16 was discovered to contain a heap buffer overflow in the component quote_for_pmake()     asm/nasm.c:856 (CVE-2022-44370)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
