stbimage is a single file MIT licensed library for processing images. The stbi_getn function reads a specified number of bytes from context (typically a file) into the specified buffer. In case the file stream points to the end, it returns zero. There are two places where its return value is not checked: In the
stbi__hdr_loadfunction and in thestbi__tga_loadfunction. The latter of the two is likely more exploitable as an attacker may also control the size of an uninitialized buffer. - References
