"The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3294
advisory.

  - In libarchive before 3.6.2, the software does not check for an error after calling calloc function that
    can return with a NULL pointer if the function fails, which leads to a resultant NULL pointer dereference.
    NOTE: the discoverer cites this CWE-476 remark but third parties dispute the code-execution impact: In
    rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it,
    then writing or reading memory is possible, which may lead to code execution. (CVE-2022-36227)

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