Описание
GStreamer is a library for constructing graphs of media-handling components. A null pointer dereference vulnerability has been identified in gst_gdk_pixbuf_dec_flush within gstgdkpixbufdec.c. This function invokes memcpy, using out_pix as the destination address. out_pix is expected to point to the frame 0 from the frame structure, which is read from the input file. However, in certain situations, it can points to a NULL frame, causing the subsequent call to memcpy to attempt writing to the null address (0x00), leading to a null pointer dereference. This vulnerability can result in a Denial of Service (DoS) by triggering a segmentation fault (SEGV). This vulnerability is fixed in 1.24.10.
A flaw was found in the gdk-pixbuf decoder in the GStreamer library. Processing a specially crafted input file can cause a NULL pointer dereference due to an unchecked return value, resulting in an application crash and a denial of service.
Отчет
To exploit this flaw, an attacker needs to trick a user into opening or processing a specially crafted file with the gdk-pixbuf decoder. As user interaction is required to trigger is issue and the impact is limited to an application crash, this flaw has been rated with a Moderate severity.
Меры по смягчению последствий
Do not process untrusted files with the gdk-pixbuf decoder and monitor application crashes as this may indicate exploitation attempts.
