  - 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)
