CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-38103 is a high-severity Integer Overflow or Wraparound (CWE-190) vulnerability in Gstreamer Gstreamer. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique LSA Secrets (T1003.004); ranked in the top 26% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
GStreamer is affected by an integer overflow vulnerability during RealMedia file parsing that can result in remote code execution. The flaw, assigned CWE-190, resides in the rmdemux module's handling of MDPR chunks where insufficient validation of attacker-controlled values permits an overflow before a buffer is allocated. The issue was reported as ZDI-CAN-21443 and carries a CVSS 3.1 score of 8.8.
Remote attackers can trigger the vulnerability by delivering a crafted RealMedia file to any application that uses the affected GStreamer library. Successful exploitation allows arbitrary code execution in the context of the consuming process; the attack requires user interaction but needs no prior authentication and can be performed over the network.
Publicly referenced patches from the GStreamer project add explicit integer-overflow checks when calculating MDPR chunk sizes, and the Zero Day Initiative advisory ZDI-23-1007 provides additional technical detail on the flaw. The associated EPSS score has remained flat at 0.0786 with no material increase observed after disclosure.

on the implementation. The specific flaw exists within the parsing of MDPR chunks. The issue results from the lack of proper validation of user-supplied data, which can result in an integer overflow before allocating a buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-21443.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (static analysis, fuzzing, unit tests) directly finds integer overflow defects before deployment.
Secure engineering principles require use of safe arithmetic constructs or language features that structurally eliminate integer overflow during calculation.
Input validation enforces bounds on values before arithmetic, stopping the conditions that trigger overflow or wraparound.
