Vulnerability Title
GStreamer MRF File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
Source: CVE Program / CVE List V5
Vulnerability 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.
