CVE-2025-7345

Name	CVE-2025-7345
Description	A flaw exists in gdk‑pixbuf within the gdk_pixbuf__jpeg_image_load_increment function (io-jpeg.c) and in glib’s g_base64_encode_step (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.
Source	CVE (at NVD; CERT, LWN, oss-sec, fulldisc, Red Hat, Ubuntu, Gentoo, SUSE bugzilla/CVE, GitHub advisories/code/issues, web search, more)
