CVE-2016-0736 [HIGH] Apache HTTP Server vulnerabilities
Title: Apache HTTP Server vulnerabilities
Summary: Several security issues were fixed in Apache HTTP Server.
It was discovered that the Apache mod_session_crypto module was encrypting
data and cookies using either CBC or ECB modes. A remote attacker could
possibly use this issue to perform padding oracle attacks. (CVE-2016-0736)
Maksim Malyutin discovered that the Apache mod_auth_digest module
incorrectly handled malicious input. A remote attacker could possibly use
this issue to cause Apache to crash, resulting in a denial of service.
(CVE-2016-2161)
David Dennerline and Régis Leroy discovered that the Apache HTTP Server
incorrectly handled unusual whitespace when parsing requests, contrary to
specifications. When being used in combination with a proxy or backend

httpd: DoS vulnerability in mod_auth_digest
In Apache HTTP Server versions 2.4.0 to 2.4.23, malicious input to mod_auth_digest can cause the server to crash, and each instance continues to crash even for subsequently valid requests.
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.
