Description
GStreamer RealMedia Demuxer Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. Interaction with this library is required to exploit this vulnerability but attack vectors may vary depending on the implementation. The specific flaw exists within the processing of video packets. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-28845.

Executive Summary

This vulnerability exists in the GStreamer RealMedia Demuxer component and involves an out-of-bounds write during the processing of video packets. It occurs because the software does not properly validate user-supplied data, which can cause it to write data past the end of an allocated buffer.

An attacker who interacts with this library can exploit this flaw to execute arbitrary code remotely within the context of the affected process.

Impact Analysis

This vulnerability can allow a remote attacker to execute arbitrary code on your system if you use the affected GStreamer component. This could lead to full compromise of the affected process, potentially allowing the attacker to take control of the system, steal data, or disrupt operations.
