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 :

  - 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 'SEGV     on unknown address' that will cause a remote denial of     service attack, because asm/preproc.c mishandles macro     calls that have the wrong number of     arguments.(CVE-2017-17810)

  - In Netwide Assembler (NASM) 2.14rc0, there is a     heap-based buffer over-read in the function detoken()     in asm/preproc.c that will cause a remote denial of     service attack.(CVE-2017-17812)

  - In Netwide Assembler (NASM) 2.14rc0, there is an     illegal address access in is_mmacro() in asm/preproc.c     that will cause a remote denial of service attack,     because of a missing check for the relationship between     minimum and maximum parameter counts.(CVE-2017-17815)

  - In Netwide Assembler (NASM) 2.14rc0, there is an     illegal address access in the function find_cc() in     asm/preproc.c that will cause a remote denial of     service attack, because pointers associated with     skip_white_ calls are not validated.(CVE-2017-17819)

  - 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)

  - Netwide Assembler (NASM) 2.14rc0 has a division-by-zero     vulnerability in the expr5 function in asm/eval.c via a     malformed input file.(CVE-2018-10016)

  - Netwide Assembler (NASM) 2.14rc0 has an endless while     loop in the assemble_file function of asm/nasm.c     because of a globallineno integer     overflow.(CVE-2018-10316)

  - 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)

  - There is an illegal address access at asm/preproc.c     (function: is_mmacro) in Netwide Assembler (NASM)     2.14rc16 that will cause a denial of service     (out-of-bounds array access) because a certain     conversion can result in a negative     integer.(CVE-2018-19755)

  - 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)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In Netwide Assembler (NASM) 2.14rc0, there is a SEGV on unknown address that will cause a remote denial     of service attack, because asm/preproc.c mishandles macro calls that have the wrong number of arguments.
