Description

This strike exploits a heap buffer overflow vulnerability in H2O Webserver. H2O Webserver has a function to allocate sufficient memory for large HTTP headers, however, in certain cases the buffer position pointer may become negative or overly large. In this case, the buffer will not be reallocated, leading to a buffer overflow. An attacker can exploit this vulnerability by sending a specially crafted HTTP message. Successful exploitation may result in arbitrary code execution or abnormal termination of the H2O Webserver, leading to a denial of service condition.
