The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2981 advisory.
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)
A null pointer dereference was discovered lzo_decompress_buf in stream.c in Irzip 0.621 which allows an attacker to cause a denial of service (DOS) via a crafted compressed file. (CVE-2020-25467)
A null pointer dereference was discovered in ucompthread in stream.c in Irzip 0.631 which allows attackers to cause a denial of service (DOS) via a crafted compressed file. (CVE-2021-27345)
Use after free in lzma_decompress_buf function in stream.c in Irzip 0.631 allows attackers to cause Denial of Service (DoS) via a crafted compressed file. (CVE-2021-27347)
lrzip v0.641 was discovered to contain a multiple concurrency use-after-free between the functions zpaq_decompress_buf() and clear_rulist(). This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted Irz file. (CVE-2022-26291)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
