AI-Generated

GStreamer is vulnerable to a heap-based buffer overflow in its MRF file parsing, which can lead to remote code execution if a user interacts with a malicious page or file. The flaw arises from inadequate validation of user-supplied data length before it is copied to a heap buffer, allowing attackers to execute arbitrary code within the context of the affected process. Organizations using GStreamer should prioritize patching this vulnerability to mitigate potential exploitation risks.

Original NVD Description

GStreamer MRF File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of GStreamer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of MRF files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a heap-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-29608.
