Red Hat Security Advisory 2017-0906-01 – The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. Security Fix: It was discovered that the mod_session_crypto module of httpd did not use any mechanisms to verify integrity of the encrypted session data stored in the user’s browser. A remote attacker could use this flaw to decrypt and modify session data using a padding oracle attack. It was discovered that the mod_auth_digest module of httpd did not properly check for memory allocation failures. A remote attacker could use this flaw to cause httpd child processes to repeatedly crash if the server used HTTP digest authentication.
