TITLE

Apache httpd In NULL Pointer dereference vulnerability

DESCRIPTION

In Apache httpd 2.2.x before 2.2.33 and 2.4.x before 2.4.26, mod_ssl may dereference a NULL pointer when third-party modules call ap_hook_process_connection() during an HTTP request to an HTTPS port. Apache httpd Is NULL A vulnerability related to pointer dereference exists.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Apache HTTP Server is prone to a denial-of-service vulnerability. Attackers may leverage this issue to cause a denial-of-service condition, denying service to legitimate users. 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-2017-3169) 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. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201710-32 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: Apache: Multiple vulnerabilities Date: October 29, 2017 Bugs: #622240, #624868, #631308 ID: 201710-32 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in Apache, the worst of which may result in the loss of secrets.

Summary: An update for httpd is now available for Red Hat Enterprise Linux 7.3 Extended Update Support. 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 Enterprise Linux ComputeNode Optional EUS (v. 7.3) - noarch, x86_64 Red Hat Enterprise Linux Server EUS (v. 7.3) - noarch, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional EUS (v. 7.3) - ppc64, ppc64le, s390x, 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-2017-9788) * It was discovered that the use of httpd's ap_get_basic_auth_pw() API function outside of the authentication phase could lead to authentication bypass. A remote attacker could possibly use this flaw to bypass required authentication if the API was used incorrectly by one of the modules used by httpd. (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 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) * A use-after-free flaw was found in the way httpd handled invalid and previously unregistered HTTP methods specified in the Limit directive used in an .htaccess file. A remote attacker could possibly use this flaw to disclose portions of the server memory, or cause httpd child process to crash. (CVE-2017-9798) Red Hat would like to thank Hanno BAPck for reporting CVE-2017-9798. 4.
