OpenSSL unknown TLS message types denial of service
| openssl-tls-dos (15509) |  Medium Risk |
Description:
OpenSSL is vulnerable to a denial of service, caused by improper handling of unknown TLS message types. A remote attacker could exploit this vulnerability to cause OpenSSL to enter an infinite loop.
Note: Any application that uses the OpenSSL's SSL/TLS library may be vulnerable.
Consequences:
Denial of Service
Remedy:
Upgrade to the latest version of OpenSSL (0.9.7d or 0.9.6m), as listed in OpenSSL Security Advisory [17 March 2004]. See References.
Recompile applications that are statically linked to OpenSSL libraries.
For other distributions:
Apply the appropriate update for your system. See References.
