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 versions of the nasm package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Netwide Assembler (NASM) 2.14rc15 has a heap-based     buffer over-read in expand_mmac_params in asm/preproc.c     for insufficient input.(CVE-2018-19214)

  - Netwide Assembler (NASM) 2.14rc16 has a heap-based     buffer over-read in expand_mmac_params in asm/preproc.c     for the special cases of the % and $ and !     characters.(CVE-2018-19215)

  - Netwide Assembler (NASM) 2.13.02rc2 has a heap-based     buffer over-read in the function tokenize in     asm/preproc.c, related to an unterminated     string.(CVE-2018-8881)

  - Netwide Assembler (NASM) 2.13.02rc2 has a stack-based     buffer under-read in the function ieee_shr in     asm/float.c via a large shift value.(CVE-2018-8882)

  - 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)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     heap-based buffer over-read that will cause a remote     denial of service attack, related to a while loop in     paste_tokens in asm/preproc.c.(CVE-2017-17818)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     heap-based buffer overflow that will cause a remote     denial of service attack, related to a strcpy in     paste_tokens in asm/preproc.c, a similar issue to     CVE-2017-11111.(CVE-2017-17811)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     use-after-free in the pp_list_one_macro function in     asm/preproc.c that will cause a remote denial of     service attack, related to mishandling of line-syntax     errors.(CVE-2017-17813)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     use-after-free in do_directive in asm/preproc.c that     will cause a remote denial of service     attack.(CVE-2017-17814)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     use-after-free in pp_getline in asm/preproc.c that will     cause a remote denial of service     attack.(CVE-2017-17816)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     use-after-free in pp_verror in asm/preproc.c that will     cause a remote denial of service     attack.(CVE-2017-17817)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     heap-based buffer over-read that will cause a remote     denial of service attack, related to a while loop in     paste_tokens in asm/preproc.c.(CVE-2017-17818)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     use-after-free in pp_list_one_macro in asm/preproc.c     that will lead to a remote denial of service attack,     related to mishandling of operand-type     errors.(CVE-2017-17820)
