"The remote Ubuntu 18.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in
the USN-5171-1 advisory.

  - The read_1g function in stream.c in liblrzip.so in lrzip 0.631 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 archive. (CVE-2017-8844)

  - The read_stream function in stream.c in liblrzip.so in lrzip 0.631 allows remote attackers to cause a
    denial of service (use-after-free and application crash) via a crafted archive. (CVE-2017-8846)

  - In lrzip 0.631, a stack buffer overflow was found in the function get_fileinfo in lrzip.c:979, which
    allows attackers to cause a denial of service via a crafted file. (CVE-2017-9928)

  - In lrzip 0.631, a stack buffer overflow was found in the function get_fileinfo in lrzip.c:1074, which
    allows attackers to cause a denial of service via a crafted file. (CVE-2017-9929)

  - In Long Range Zip (aka lrzip) 0.631, there is an infinite loop and application hang in the unzip_match
    function in runzip.c. Remote attackers could leverage this vulnerability to cause a denial of service via
    a crafted lrz file. (CVE-2018-5650)

  - In Long Range Zip (aka lrzip) 0.631, there is a use-after-free in the ucompthread function (stream.c).
    Remote attackers could leverage this vulnerability to cause a denial of service via a crafted lrz file.
    (CVE-2018-5747)

  - In Long Range Zip (aka lrzip) 0.631, there is an infinite loop and application hang in the get_fileinfo
    function (lrzip.c). Remote attackers could leverage this vulnerability to cause a denial of service via a
    crafted lrz file. (CVE-2018-5786)

  - In Long Range Zip (aka lrzip) 0.631, there is a use-after-free in the lzma_decompress_buf function of
    stream.c, which allows remote attackers to cause a denial of service (application crash) or possibly have
    unspecified other impact. (CVE-2018-10685)

  - In Long Range Zip (aka lrzip) 0.631, there is a use-after-free in read_stream in stream.c, because
    decompress_file in lrzip.c lacks certain size validation. (CVE-2018-11496)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
