Vulnerability from variot - Updated: 2025-12-22 21:54
When apr_time_exp() or apr_os_exp_time() functions are invoked with an invalid month field value in Apache Portable Runtime APR 1.6.2 and prior, out of bounds memory may be accessed in converting this value to an apr_time_exp_t value, potentially revealing the contents of a different static heap value or resulting in program termination, and may represent an information disclosure or denial of service vulnerability to applications which call these APR functions with unvalidated external input. Apache Portable Runtime Contains a buffer error vulnerability.Information is obtained and service operation is interrupted (DoS) There is a possibility of being put into a state. Apache Portable Runtime Utility is prone to multiple information-disclosure vulnerabilities. An attacker can exploit these issues to obtain sensitive information that may aid in further attacks. Failed exploit attempts will result in denial-of-service conditions. Apache Portable Runtime Utility (APR-util) 1.6.2 and prior versions are vulnerable. 7.2) - x86_64

The References section of this erratum contains a download link (you must log in to download the update). Before applying the update, back up your existing Red Hat JBoss Web Server installation (including all applications and configuration files). Summary:
An update is now available for JBoss Core Services on RHEL 7. 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.
This release of Red Hat JBoss Core Services Apache HTTP Server 2.4.23 Service Pack 3 serves as an update to Red Hat JBoss Core Services Apache HTTP Server 2.4.23 Service Pack 2, and includes bug fixes, which are documented in the Release Notes document linked to in the References. (CVE-2017-12613)
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 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)
