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.

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 5 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: heap-based buffer over-read in do_directive in asm/preproc.c (CVE-2018-19215)

  - nasm: Buffer over-read in parse_line function in asm/parser.c (CVE-2018-8883)

  - 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.

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.

The remote host is affected by the vulnerability described in GLSA-201903-19 (NASM: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in NASM. Please review the       CVE identifiers referenced below for details.
  Impact :

    A remote attacker could cause a Denial of Service condition or execute       arbitrary code.
  Workaround :

    There is no known workaround at this time.

The remote Ubuntu 14.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3694-1 advisory.

    It was discovered that NASM incorrectly handled certain source files. If a user or automated system were     tricked into processing a specially crafted source file, a remote attacker could use these issues to cause     NASM to crash, resulting in a denial of service, or possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

According to the version of the nasm package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - 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 Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
