High Nessus Plugin ID 101062


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


Emmanuel Dreyfus discovered that third-party modules using the ap_get_basic_auth_pw() function outside of the authentication phase may lead to authentication requirements being bypassed. This update adds a new ap_get_basic_auth_components() function for use by third-party modules. (CVE-2017-3167)

Vasileios Panopoulos discovered that the Apache mod_ssl module may crash when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. (CVE-2017-3169)

Javier Jimenez discovered that the Apache HTTP Server incorrectly handled parsing certain requests. A remote attacker could possibly use this issue to cause the Apache HTTP Server to crash, resulting in a denial of service. (CVE-2017-7668)

ChenQin and Hanno Bock discovered that the Apache mod_mime module incorrectly handled certain Content-Type response headers. A remote attacker could possibly use this issue to cause the Apache HTTP Server to crash, resulting in a denial of service. (CVE-2017-7679).

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.
