How to fix?

Upgrade Alpine:3.22 php84 to version 8.4.16-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php84 package and not the php84 package as distributed by Alpine. See How to fix? for Alpine:3.22 relevant fixed versions and status.

In PHP versions:8.1.* before 8.1.34, 8.2.* before 8.2.30, 8.3.* before 8.3.29, 8.4.* before 8.4.16, 8.5.* before 8.5.1, the getimagesize() function may leak uninitialized heap memory into the APPn segments (e.g., APP1) when reading images in multi-chunk mode (such as via php://filter). This occurs due to a bug in php_read_stream_all_chunks() that overwrites the buffer without advancing the pointer, leaving tail bytes uninitialized. This may lead to information disclosure of sensitive heap data and affect the confidentiality of the target server.
