What is CVE-2021-36530?

The ngiflib version 0.4 contains a heap overflow vulnerability in the GetByteStr() function, located at ngiflib.c:108. This issue arises when using NGIFLIB_NO_FILE mode, as it allows the GetByteStr() function to copy a memory buffer without adequate boundary checks.

It is essential for users and administrators to address this vulnerability promptly to safeguard their systems.
