Alpine: py3-ujson: security update to 5.4.0-r0

high Tenable Self-Hosted Container Security Plugin ID 406717

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. Affected
 versions were found to improperly decode certain characters. JSON strings that contain escaped surrogate
 characters not part of a proper surrogate pair were decoded incorrectly. Besides corrupting strings, this
 allowed for potential key confusion and value overwriting in dictionaries. All users parsing JSON from
 untrusted sources are vulnerable. From version 5.4.0, UltraJSON decodes lone surrogates in the same way as
 the standard library's `json` module does, preserving them in the parsed output. Users are advised to
 upgrade. There are no known workarounds for this issue. (CVE-2022-31116)

 - UltraJSON is a fast JSON encoder and decoder written in pure C with bindings for Python 3.7+. In versions
 prior to 5.4.0 an error occurring while reallocating a buffer for string decoding can cause the buffer to
 get freed twice. Due to how UltraJSON uses the internal decoder, this double free is impossible to trigger
 from Python. This issue has been resolved in version 5.4.0 and all users should upgrade to UltraJSON
 5.4.0. There are no known workarounds for this issue. (CVE-2022-31117)
