Detailsinfo

A vulnerability was found in stb_image (version unknown). It has been classified as problematic. Affected is the function stbi__getn. The manipulation with an unknown input leads to a uninitialized resource vulnerability. CWE is classifying the issue as CWE-908. The product uses or accesses a resource that has not been initialized. This is going to have an impact on confidentiality. CVE summarizes:

stb_image 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_load` function and in the `stbi__tga_load` function. The latter of the two is likely more exploitable as an attacker may also control the size of an uninitialized buffer.

The weakness was released 10/21/2023 as GHSL-2023-145. The advisory is shared for download at securitylab.github.com. This vulnerability is traded as CVE-2023-45663 since 10/10/2023.
