Ubuntu 14.04 LTS / 16.04 LTS : Apache HTTP Server vulnerabilities (USN-3279-1)

high Nessus Plugin ID 100098

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3279-1 advisory.

 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 Rgis 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
