  - 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)

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5840-1 advisory.

    It was discovered that Long Range ZIP incorrectly handled pointers. If

    a user or an automated system were tricked into opening a certain

    specially crafted ZIP file, an attacker could possibly use this issue to cause a denial of service. This     issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM, Ubuntu 18.04 LTS, and Ubuntu 20.04 LTS.

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2981 advisory.

    Several security vulnerabilities have been discovered in lrzip, a compression program. Invalid pointers,     use-after-free and infinite loops would allow attackers to cause a denial of service or possibly other     unspecified impact via a crafted compressed file. CVE-2018-5786 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-2020-25467 A null pointer dereference was discovered     lzo_decompress_buf in stream.c which allows an attacker to cause a denial of service (DOS) via a crafted     compressed file. CVE-2021-27345 A null pointer dereference was discovered in ucompthread in stream.c which     allows attackers to cause a denial of service (DOS) via a crafted compressed file. CVE-2021-27347 Use     after free in lzma_decompress_buf function in stream.c in allows attackers to cause Denial of Service     (DoS) via a crafted compressed file. CVE-2022-26291 lrzip 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 lrz file. For Debian 9 stretch, these problems     have been fixed in version 0.631-1+deb9u2.
