Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, does not sign all required data in requests, which has unspecified impact, probably related to man-in-the-middle attacks that modify critical data and allow remote attackers to impersonate other users and gain privileges.

Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, does not use timeouts for signed requests, which allows remote attackers to impersonate other users and gain privileges via a replay attack that sends the same request.

Services 5.x before 5.x-0.92 and 6.x before 6.x-0.13, a module for Drupal, uses an insecure hash when signing requests, which allows remote attackers to impersonate other users and gain privileges.

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.
