CVE-2024-0444
Description
A stack-based buffer overflow flaw was found in GStreamer. This issue may lead to code execution while parsing tile list data within AV1-encoded video files.
Statement
Despite the potential for remote code execution, the CVE-2024-0444 vulnerability in GStreamer is classified with a Moderate severity due to the high attack complexity (AC) and the requirement for user interaction (UI). Exploitation of this vulnerability is not straightforward; an attacker must craft a specific AV1-encoded video file and persuade a user to process it with the vulnerable GStreamer implementation. Additionally, the need for precise manipulation of stack-based buffer operations to achieve arbitrary code execution adds further complexity, reducing the likelihood of successful exploitation in real-world scenarios. The requirement for user interaction and the high complexity barrier mitigate the overall risk, hence the Moderate severity rating.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).

Understanding the Weakness (CWE)
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU); DoS: Resource Consumption (Memory)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the program into an infinite loop.
Integrity,Confidentiality,Availability,Access Control
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of a program's implicit security policy.
Integrity,Confidentiality,Availability,Access Control,Other
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands; Bypass Protection Mechanism; Other
When the consequence is arbitrary code execution, this can often be used to subvert any other security service.
