Unspecified vulnerability in the IP-authentication feature in the Secure Site 5.x-1.0 and 4.7.x-1.0 module for Drupal allows remote attackers to gain the privileges of a user who has authenticated from behind the same proxy server as the attacker.

Unspecified vulnerability in the Secure site 4.7.x-1.x-dev and 5.x-1.x-dev module for Drupal allows remote attackers to bypass access restrictions via a crafted URL.

The SSL/TLS handshaking code in OpenSSL 0.9.7a, 0.9.7b, and 0.9.7c, when using Kerberos ciphersuites, does not properly check the length of Kerberos tickets during a handshake, which allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that causes an out-of-bounds read.

The do_change_cipher_spec function in OpenSSL 0.9.6c to 0.9.6k, and 0.9.7a to 0.9.7c, allows remote attackers to cause a denial of service (crash) via a crafted SSL/TLS handshake that triggers a null dereference.

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.
