Description
A vulnerability was found in WebKitGTK. This issue occurs due to a logic issue in video self-preview feature in a webRTC call, which can be interrupted if the user answers a phone call or the audio capture is interrupted. This flaw allows a remote attacker to perform a denial of service attack.
Statement
The vulnerability does not affect RHEL because WebRTC code is not included in any WebKitGTK releases thus far.
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,Other
Technical Impact: DoS: Resource Consumption (Other); Varies by Context
Most unreleased resource issues result in general software reliability problems, but if an attacker can intentionally trigger a resource leak, the attacker might be able to launch a denial of service attack by depleting the resource pool.
Confidentiality
Technical Impact: Read Application Data
When a resource containing sensitive information is not correctly shutdown, it may expose the sensitive data in a subsequent allocation.
