Assigner: Red Hat, Inc.

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.

AI Powered Q&A
Can you explain this vulnerability to me?

This vulnerability is a flaw in gdk-pixbuf's JPEG image loading function and glib's Base64 encoding step. When processing specially crafted malicious JPEG images, it can cause a heap buffer overflow during Base64 encoding, leading to out-of-bounds reads from heap memory. This can result in application crashes or allow an attacker to execute arbitrary code.


How can this vulnerability impact me? :

The vulnerability can cause applications that use gdk-pixbuf to crash unexpectedly or, worse, allow attackers to execute arbitrary code on the affected system. This could lead to system compromise or denial of service.
