CVE-2026-18296: GStreamer MRF File Parsing Heap-based Buffer Overflow Remote Code Execution Vulnerability
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.

Frequently Asked Questions
Does exploitation require an attacker to authenticate or have existing access to the target system?
No. The vulnerability is rated with no privileges required, but exploitation requires the target to visit a malicious page or open a malicious file.
What is the impact if exploitation succeeds?
An attacker can execute arbitrary code in the context of the current process. The provided severity vector indicates high confidentiality, integrity, and availability impact.
Which content should be treated as the attack vector during triage?
The vulnerable component is the parser for MRF files. Malicious MRF content delivered through a webpage or file-opening workflow is the relevant exposure path.
