Description

The SSL/TLS handshaking code in OpenSSL does not properly check the length of Kerberos tickets during an SSL/TLS handshake when using Kerberos ciphersuites. This allows remote attackers to cause a denial of service by manipulating the parameters during SSL/TLS handshake, causing an out-of-bounds read and crashing OpenSSL.
