========================================================================== Ubuntu Security Notice USN-3279-1 May 09, 2017
apache2 vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10 - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
Several security issues were fixed in Apache HTTP Server.
Software Description: - apache2: Apache HTTP server
Details:
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 server, a remote attacker could possibly use this issue to perform an injection attack and pollute cache. This update may introduce compatibility issues with clients that do not strictly follow HTTP protocol specifications. A new configuration option "HttpProtocolOptions Unsafe" can be used to revert to the previous unsafe behaviour in problematic environments. (CVE-2016-8743)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.10: apache2-bin 2.4.18-2ubuntu4.1
Ubuntu 16.04 LTS: apache2-bin 2.4.18-2ubuntu3.2
Ubuntu 14.04 LTS: apache2-bin 2.4.7-1ubuntu4.14
In general, a standard system update will make all the necessary changes.
