Off-by-one error in Steamcast 0.9.75 and earlier allows remote attackers to cause a denial of service (daemon crash) or execute arbitrary code via a certain HTTP request that leads to a buffer overflow, as demonstrated by a long User-Agent header.
This Metasploit module exploits a stack overflow in Streamcast <= 0.9.75. By sending an overly long User-Agent in a HTTP GET request, an attacker may be able to execute arbitrary code.
