Secure Sockets Layer message denial of service
| ssl-message-dos (15712) |  Medium Risk |
Description:
Multiple vendor applications are vulnerable to a denial of service. The Secure Sockets Layer (SSL) library fails to properly check user-supplied input in SSL messages. If SSL is enabled, a remote attacker could send a specially-crafted SSL message to the vulnerable system to cause a denial of service.
Note: On Microsoft Windows 2000 and Windows XP, an attacker could cause the system to stop accepting SSL connections. On Microsoft Windows Server 2003, an attacker could cause the affected system to restart automatically.
Platforms Affected:
- Microsoft, Windows 2000
- Microsoft, Windows 2003 Server
- Microsoft, Windows XP
Remedy:
Apply the appropriate patch for your system, as listed in Microsoft Security Bulletin MS04-011. See References.
Consequences:
Denial of Service
