CVE-2017-9788

TITLE

Apache httpd Security hole

DESCRIPTION

In Apache httpd before 2.2.34 and 2.4.x before 2.4.27, the value placeholder in [Proxy-]Authorization headers of type 'Digest' was not initialized or reset before or between successive key=value assignments by mod_auth_digest. Providing an initial key with no '=' assignment could reflect the stale value of uninitialized pool memory used by the prior request, leading to leakage of potentially confidential information, and a segfault in other cases resulting in denial of service. Apache HTTP Server is prone to a memory-corruption vulnerability. Attackers can exploit this issue to cause to obtain sensitive information or cause denial-of-service conditions. Versions prior to Apache httpd 2.2.34 and 2.4.27 are vulnerable. This software, such as Apache HTTP Server, is common to multiple JBoss middleware products, and is packaged under Red Hat JBoss Core Services to allow for faster distribution of updates, and for a more consistent update experience. An httpd module using this API function could consequently allow access that should have been denied. JIRA issues fixed (https://issues.jboss.org/): JBCS-329 - Unable to load large CRL openssl problem JBCS-336 - Errata for httpd 2.4.23 SP2 RHEL 7 7. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library. Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies. The updates are documented in the Release Notes document linked to in the References. This release of Red Hat JBoss Web Server 2.1.2 Service Pack 2 serves as a update for Red Hat JBoss Web Server 2, and includes bug fixes, which are documented in the Release Notes document linked to in the References. (CVE-2017-9788) * A vulnerability was discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution. (CVE-2017-12615) * A vulnerability was discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution. (CVE-2017-12617) * A flaw was found in the way the DES/3DES cipher was used as part of the TLS/SSL protocol. A man-in-the-middle attacker could use this flaw to recover some plaintext data by capturing large amounts of encrypted traffic between TLS/SSL server and client if the communication used a DES/3DES based ciphersuite. (CVE-2016-2183) * 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. (CVE-2017-9798) Red Hat would like to thank OpenVPN for reporting CVE-2016-2183 and Hanno BAPck for reporting CVE-2017-9798. Upstream acknowledges Karthikeyan Bhargavan (Inria) and GaA<<tan Leurent (Inria) as the original reporters of CVE-2016-2183. Bug Fix(es): * Corruption in nodestatsmem in multiple core dumps but in different functions of each core dump. (BZ#1338640) * mod_cluster segfaults in process_info() due to wrongly generated assembler instruction movslq (BZ#1448709) * CRL checking of very large CRLs fails with OpenSSL 1.0.2 (BZ#1493075) 4. Solution: Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). Bugs fixed (https://bugzilla.redhat.com/): 1369383 - CVE-2016-2183 SSL/TLS: Birthday attack against 64-bit block ciphers (SWEET32) 1470748 - CVE-2017-9788 httpd: Uninitialized memory reflection in mod_auth_digest 1490344 - CVE-2017-9798 httpd: Use-after-free by limiting unregistered HTTP method (Optionsbleed) 1493075 - Unable to load large CRL openssl problem 1493220 - CVE-2017-12615 tomcat: Remote Code Execution via JSP Upload 1494283 - CVE-2017-12617 tomcat: Remote Code Execution bypass for CVE-2017-12615 6. 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-2017-9788) * 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 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.
