How to fix?

Upgrade Alpine:3.15 curl to version 7.51.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream curl package and not the curl package as distributed by Alpine. See How to fix? for Alpine:3.15 relevant fixed versions and status.

The libcurl API function called curl_maprintf() before version 7.51.0 can be tricked into doing a double-free due to an unsafe size_t multiplication, on systems using 32 bit size_t variables.
