Описание
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.
Отчет
The Red Hat Product Security team has rated this vulnerability as Moderate.The flaw, identified in gdk-pixbuf, allows remote attackers to trigger a denial of service by supplying a specially crafted image file. This issue stems from improper bounds handling during image decoding. While exploitable without authentication, it does not lead to data compromise or code execution.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
