gdk-pixbuf

A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions.

CVE-2026-5201 is a heap-based buffer overflow vulnerability in the gdk-pixbuf2 library's JPEG image loader. The vulnerability arises from improper validation of color component counts when processing maliciously crafted JPEG images. This can be exploited remotely without user interaction, for example during thumbnail generation, leading to application crashes and denial of service. Red Hat Enterprise Linux versions 9 (up to but not including 9.8) and 10 (up to but not including 10.2) are affected. Red Hat has issued security advisories RHSA-2026:10707 and RHSA-2026:10708 providing updated gdk-pixbuf2 packages that fix this vulnerability across multiple architectures including x86_64, s390x, ppc64le, and aarch64.

CVE-2026-5201: Heap-based Buffer Overflow in Red Hat Red Hat Enterprise Linux 10

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.

The vulnerability CVE-2025-7345 affects the gdk-pixbuf2 library used in Red Hat Enterprise Linux 9 and 10. It involves a heap buffer overflow in the gdk_pixbuf__jpeg_image_load_increment function and glib's g_base64_encode_step when handling specially crafted JPEG images. This overflow can result in out-of-bounds reads from heap memory, which may cause application crashes or enable arbitrary code execution. Red Hat has issued security advisories RHSA-2025:12841 and RHSA-2025:12862 providing updated gdk-pixbuf2 packages that fix this issue. The updates are rated with a Moderate security impact by Red Hat but the CVSS v3.1 score is 7.5 (High) with an attack vector of network, no privileges required, and no user interaction needed.
