Ubuntu 14.04 LTS / 16.04 LTS / 17.04 : apache2 vulnerability (USN-3425-1) (Optionsbleed)

Medium Nessus Plugin ID 103356


The remote Ubuntu host is missing a security-related patch.


Hanno Bock discovered that the Apache HTTP Server incorrectly handled Limit directives in .htaccess files. In certain configurations, a remote attacker could possibly use this issue to read arbitrary server memory, including sensitive information. This issue is known as Optionsbleed.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected apache2-bin package.
