TITLE

Apache httpd Vulnerabilities in authentication

DESCRIPTION

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, use of the ap_get_basic_auth_pw() by third-party modules outside of the authentication phase may lead to authentication requirements being bypassed. Apache httpd Contains an authentication vulnerability.Information is acquired, information is falsified, and denial of service (DoS) May be in a state. Apache HTTP Server is prone to an authentication bypass vulnerability. An attacker can exploit this issue to bypass authentication mechanism and perform unauthorized actions. This may lead to further attacks. The following versions are vulnerable: Apache HTTP Server 2.2.0 to 2.2.32 Apache HTTP Server 2.4.0 to 2.4.25. ========================================================================== Ubuntu Security Notice USN-3373-1 July 31, 2017 apache2 vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 12.04 ESM Summary: Several security issues were fixed in Apache HTTP Server. 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 JimA(c)nez discovered that the Apache HTTP Server incorrectly handled parsing certain requests. (CVE-2017-7679) David Dennerline and RA(c)gis Leroy discovered that the Apache HTTP Server incorrectly handled unusual whitespace when parsing requests, contrary to specifications. 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 12.04 ESM: A apache2.2-binA A A A A A A A A A A A A A A A A A A 2.2.22-1ubuntu1.12 In general, a standard system update will make all the necessary changes. 7) - x86_64 3. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: httpd24-httpd security update Advisory ID: RHSA-2017:2483-01 Product: Red Hat Software Collections Advisory URL: https://access.redhat.com/errata/RHSA-2017:2483 Issue date: 2017-08-16 CVE Names: CVE-2017-3167 CVE-2017-3169 CVE-2017-7659 CVE-2017-7668 CVE-2017-7679 CVE-2017-9788 ===================================================================== 1. Summary: An update for httpd24-httpd is now available for Red Hat Software Collections. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section. 2. Relevant releases/architectures: Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server (v. 7) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 6.7) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Server EUS (v. 7.3) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 6) - noarch, x86_64 Red Hat Software Collections for Red Hat Enterprise Linux Workstation (v. 7) - noarch, x86_64 3. Security Fix(es): * It was discovered that the httpd's mod_auth_digest module did not properly initialize memory before using it when processing certain headers related to digest authentication. A remote attacker could possibly use this flaw to disclose potentially sensitive information or cause httpd child process to crash by sending specially crafted requests to a server. (CVE-2017-3167) * A NULL pointer dereference flaw was found in the httpd's mod_ssl module. A remote attacker could use this flaw to cause an httpd child process to crash if another module used by httpd called a certain API function during the processing of an HTTPS request. (CVE-2017-3169) * A NULL pointer dereference flaw was found in the mod_http2 module of httpd. A remote attacker could use this flaw to cause httpd child process to crash via a specially crafted HTTP/2 request. (CVE-2017-7659) * A buffer over-read flaw was found in the httpd's ap_find_token() function. A remote attacker could use this flaw to cause httpd child process to crash via a specially crafted HTTP request. (CVE-2017-7668) * A buffer over-read flaw was found in the httpd's mod_mime module. A user permitted to modify httpd's MIME configuration could use this flaw to cause httpd child process to crash. (CVE-2017-7679) 4. Solution: For details on how to apply this update, which includes the changes described in this advisory, refer to: https://access.redhat.com/articles/11258 After installing the updated packages, the httpd daemon will be restarted automatically. 5.
