Alpine: multiple openbao packages: security update to 2.4.1-r0

high Tenable Self-Hosted Container Security Plugin ID 435757

Description

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

 - OpenBao is an open source identity-based secrets management system. In OpenBao versions prior to 2.4.1,
 JSON objects after decoding may use significantly more memory than their serialized version. It is
 possible to craft a JSON payload to maximize the factor between serialized memory usage and deserialized
 memory usage, similar to a zip bomb, with factors reaching approximately 35. This can be used to
 circumvent the max_request_size configuration parameter which is intended to protect against denial of
 service attacks. The request body is parsed into a map very early in the request handling chain before
 authentication, which means an unauthenticated attacker can send a specifically crafted JSON object and
 cause an out-of-memory crash. Additionally, for requests with large numbers of strings, the audit
 subsystem can consume large quantities of CPU. The vulnerability is fixed in version 2.4.1.
