How to fix?

There is no fixed version for Debian:12 libstb.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libstb package and not the libstb package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

An issue was discovered in stb stb_image.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to a buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stb_image, or read up to 1024 bytes of non-consecutive heap data without control over the read location.
