libstb.so is vulnerable to Information Disclosure. The stbi__getn function reads a specified number of bytes from context into the specified buffer. When the file stream points to the end, it returns zero which allows a remote attacker to gain access to sensitive information via the exploitable stbi__hdr_loda and stbi__tga_load functions where the return value from stbi__getn is not checked.
