Summary
[none]
Details

A flaw exists in gdk‑pixbuf within the gdk_pixbuf__jpegimageloadincrement function (io-jpeg.c) and in glib’s gbase64encodestep (glib/gbase64.c). When processing maliciously crafted JPEG images, a heap buffer overflow can occur during Base64 encoding, allowing out-of-bounds reads from heap memory, potentially causing application crashes or arbitrary code execution.
