AI-suggested
Red Hat has released official security updates for gdk-pixbuf2 that address CVE-2025-7345. Users of Red Hat Enterprise Linux 9 and 10 should apply the updated packages as described in advisories RHSA-2025:12841 and RHSA-2025:12862. The updates fix the heap buffer overflow vulnerability. No additional mitigation is required beyond applying these official patches.
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.
