Description OSIDB Bzimport 2025-07-08 06:13:11 UTC 
Heap‑buffer‑overflow vulnerability in the JPEG and Base64 decoding paths of gdk‑pixbuf. The flaw occurs in gdk_pixbuf__jpeg_image_load_increment() (io‑jpeg.c:1193:26) when a specially crafted JPEG triggers a flow that leads to g_base64_encode_step() in glib (gbase64.c:141:16), reading beyond heap buffer bounds. Exploitation requires no authentication and could lead to application crash or arbitrary code execution via crafted images.
