Heap-based Buffer Overflow in WebRTC TextRtpPayloadDecoderNode

Executive Summary

This vulnerability exists in the function TextRtpPayloadDecoderNode::DecodeT140 within the TextRtpPayloadDecoderNode.cpp file. It is caused by a missing bounds check which can result in an out of bounds write.

An out of bounds write means that the program writes data outside the allocated memory buffer, which can corrupt memory and potentially allow an attacker to execute arbitrary code.

Exploitation of this vulnerability can lead to remote code execution without requiring any additional execution privileges or user interaction.

Impact Analysis

This vulnerability can allow an attacker to execute arbitrary code remotely on the affected system.

Since no user interaction or additional privileges are needed, the attacker could potentially take full control of the system or application running the vulnerable code.

This could lead to data theft, system compromise, or disruption of services depending on the context in which the vulnerable software is used.
