Alpine: php8: security update to 8.0.29-r0 (deprecated)

critical Tenable Cloud Security Plugin ID 400095

Description

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

- In PHP versions 8.0.* before 8.0.30, 8.1.* before 8.1.22, and 8.2.* before 8.2.8 various XML functions
rely on libxml global state to track configuration variables, like whether external entities are loaded.
This state is assumed to be unchanged unless the user explicitly changes it by calling appropriate
function. However, since the state is process-global, other modules - such as ImageMagick - may also use
this library within the same process, and change that global state for their internal purposes, and leave
it in a state where external entities loading is enabled. This can lead to the situation where external
XML is parsed with external entities loaded, which can lead to disclosure of any local files accessible to
PHP. This vulnerable state may persist in the same process across many requests, until the process is shut
down. (CVE-2023-3823)

- In PHP version 8.0.* before 8.0.30, 8.1.* before 8.1.22, and 8.2.* before 8.2.8, when loading phar file,
while reading PHAR directory entries, insufficient length checking may lead to a stack buffer overflow,
leading potentially to memory corruption or RCE. (CVE-2023-3824)
