Alpine: cryptsetup: security update to 2.2.2-r1

high Tenable Self-Hosted Container Security Plugin ID 403919

Description

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

- A vulnerability was found in upstream release cryptsetup-2.2.0 where, there's a bug in LUKS2 format
validation code, that is effectively invoked on every device/image presenting itself as LUKS2 container.
The bug is in segments validation code in file 'lib/luks2/luks2_json_metadata.c' in function
hdr_validate_segments(struct crypt_device *cd, json_object *hdr_jobj) where the code does not check for
possible overflow on memory allocation used for intervals array (see statement "intervals =
malloc(first_backup * sizeof(*intervals));"). Due to the bug, library can be *tricked* to expect such
allocation was successful but for far less memory then originally expected. Later it may read data FROM
image crafted by an attacker and actually write such data BEYOND allocated memory. (CVE-2020-14382)
