{"id":"USN-3279-1","summary":"apache2 vulnerabilities","details":"It was discovered that the Apache mod_session_crypto module was encrypting\ndata and cookies using either CBC or ECB modes. A remote attacker could\npossibly use this issue to perform padding oracle attacks. (CVE-2016-0736)\n\nMaksim Malyutin discovered that the Apache mod_auth_digest module\nincorrectly handled malicious input. A remote attacker could possibly use\nthis issue to cause Apache to crash, resulting in a denial of service.\n(CVE-2016-2161)\n\nDavid Dennerline and Régis Leroy discovered that the Apache HTTP Server\nincorrectly handled unusual whitespace when parsing requests, contrary to\nspecifications. When being used in combination with a proxy or backend\nserver, a remote attacker could possibly use this issue to perform an\ninjection attack and pollute cache. This update may introduce compatibility\nissues with clients that do not strictly follow HTTP protocol\nspecifications. A new configuration option \"HttpProtocolOptions Unsafe\" can\nbe used to revert to the previous unsafe behaviour in problematic\nenvironments.
