The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2725 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 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)

  • 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)

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