Description

A heap‑based buffer overflow exists in libjpeg‑turbo’s h2v2_merged_upsample_internal() function when processing 12‑bit lossless JPEG images. An attacker could craft an image containing out‑of‑range 12‑bit samples that, when decompressed with merged upsampling enabled, may trigger a segmentation fault or buffer overflow, resulting in an application crash.
