How to fix?
Upgrade Alpine:3.19 expat to version 2.2.7-r1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream expat package and not the expat package as distributed by Alpine.
See How to fix? for Alpine:3.19 relevant fixed versions and status.
In libexpat before 2.2.8, crafted XML input could fool the parser into changing from DTD parsing to document parsing too early; a consecutive call to XML_GetCurrentLineNumber (or XML_GetCurrentColumnNumber) then resulted in a heap-based buffer over-read.
