Detailsinfo

A vulnerability was found in stb_image (unknown version). It has been classified as critical. This affects the function stbi__load_gif_main_outofmem of the component Image Handler. The manipulation with an unknown input leads to a double free vulnerability. CWE is classifying the issue as CWE-415. The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

stb_image is a single file MIT licensed library for processing images. A crafted image file can trigger `stbi__load_gif_main_outofmem` attempt to double-free the out variable. This happens in `stbi__load_gif_main` because when the `layers * stride` value is zero the behavior is implementation defined, but common that realloc frees the old memory and returns null pointer. Since it attempts to double-free the memory a few lines below the first “free”, the issue can be potentially exploited only in a multi-threaded environment. In the worst case this may lead to code execution.

The weakness was disclosed 10/21/2023 as GHSL-2023-145. It is possible to read the advisory at securitylab.github.com. This vulnerability is uniquely identified as CVE-2023-45664 since 10/10/2023.
