Several problems have been found in OpenSSL. While parsing certain invalid ASN.1 |
|
structures an error condition is mishandled, possibly resulting in an infinite |
|
loop. A buffer overflow exists in the SSL_get_shared_ciphers function. A NULL |
|
pointer may be dereferenced in the SSL version 2 client code. In addition, many |
|
applications using OpenSSL do not perform any validation of the lengths of |
|
public keys being used. |
