What is CVE-2019-14872?

The _dtoa_r function of the newlib libc library prior to version 3.3.0 has multiple memory allocations that do not appropriately check the return values. This oversight could lead to potential NULL pointer dereferences, resulting in application crashes or unpredictable behavior. It is crucial for developers using affected versions to address these vulnerabilities to ensure their applications can handle memory allocation failures gracefully.
