Debian LTS Advisory ([SECURITY] [DLA 1009-1] apache2 security update)

Published: 2018-02-04 23:00:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Solution Type:
Vendor Patch

Detection Type:
Linux Distribution Package

Affected Versions:
apache2 on Debian Linux

Recommendations:
For Debian 7 'Wheezy', these problems have been fixed in version 2.2.22-13+deb7u9. We recommend that you upgrade your apache2 Linux Distribution Packages.

Summary:
Several vulnerabilities have been found in the Apache HTTPD server. CVE-2017-3167 Emmanuel Dreyfus reported that the use of ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. CVE-2017-3169 Vasileios Panopoulos of AdNovum Informatik AG discovered that mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port leading to a denial of service. CVE-2017-7668 Javier Jimenez reported that the HTTP strict parsing contains a flaw leading to a buffer overread in ap_find_token(). A remote attacker can take advantage of this flaw by carefully crafting a sequence of request headers to cause a segmentation fault, or to force ap_find_token() to return an incorrect value. CVE-2017-7679 ChenQin and Hanno Boeck reported that mod_mime can read one byte past the end of a buffer when sending a malicious Content-Type response header.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
