CVE-2022-36227

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.”
