Alpine: multiple libarchive packages: security update to 3.6.1-r1 (deprecated)

critical Tenable Cloud Security Plugin ID 409881

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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)
